Apache: Security Vulnerabilities
Untrusted Java Deserialization in Apache OpenNLP SvmDoccatModel
Versions Affected:
before 3.0.0-M4 (libsvm document categorization module; introduced in
OPENNLP-1808 and only present on the 3.x line)
Description:
SvmDoccatModel.deserialize(InputStream) reads an attacker-controlled
stream with java.io.ObjectInputStream and calls readObject() without an
ObjectInputFilter installed. ObjectInputStream materialises every class
referenced in the stream before the resulting object is cast to
SvmDoccatModel, so the cast that follows readObject() executes only
after the foreign object graph has already been deserialised in full.
If a Java deserialization gadget chain is available on the consumer's
classpath, a crafted payload supplied to
deserialize() executes arbitrary code in the JVM that loads it. Apache
OpenNLP itself does not ship a known gadget chain, so the realistic
risk is to downstream applications that embed the libsvm module
alongside vulnerable transitive dependencies. The method is public and
static, so any caller can pass an untrusted stream to it directly.
The practical impact is remote code execution against processes that
load SvmDoccatModel instances from untrusted or semi-trusted origins.
Mitigation:
3.x users should upgrade to 3.0.0-M4.
Users who cannot upgrade immediately should treat all serialized
SvmDoccatModel streams as untrusted input unless their provenance is
verified, and should avoid invoking SvmDoccatModel.deserialize() on
streams supplied by end users or fetched from third-party sources
without integrity checks.

Apache Airflow's Google provider operators `GCSToSFTPOperator` and `GCSTimeSpanFileTransformOperator` joined GCS object names returned by the bucket listing API directly to a destination filesystem path without normalisation or containment check. A user with write access to the source GCS bucket (typically a different trust principal than the DAG author — partner uploads, ingest-only service accounts, public-data buckets) could create an object whose name contains `..` segments and cause the DAG run to write the downloaded blob outside the configured destination (the SFTP `destination_path` for `GCSToSFTPOperator`; the worker-local temp directory for `GCSTimeSpanFileTransformOperator`), enabling overwrite of arbitrary files on the SFTP server or the worker host. Affects deployments that ingest from buckets writable by less-trusted principals. Users are advised to upgrade to `apache-airflow-providers-google` 22.2.1 or later.

Improper Input Validation, Authorization Bypass Through User-Controlled Key vulnerability in Apache Camel JIRA component.
The camel-jira producers read their operation parameters - the issue key, project key, transition id, summary, type, assignee, components, watchers, link type, work-log minutes and others - from Exchange message headers. The header constants defined in JiraConstants (for example ISSUE_KEY = IssueKey, ISSUE_PROJECT_KEY = ProjectKey, ISSUE_TRANSITION_ID = IssueTransitionId, LINK_TYPE = linkType) used plain, non-Camel-prefixed values. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a jira: producer, any HTTP client could therefore supply these headers and override the values the route intended, driving JIRA operations against the configured JIRA instance with the endpoint's configured service-account credentials - for example deleting or transitioning an arbitrary issue (via IssueKey / IssueTransitionId), creating an issue in a different project (via ProjectKey), modifying issue fields, adding or removing watchers, or logging work. The operations are bounded by what the configured service account is permitted to do. No credentials are required from the attacker when the bridging consumer is unauthenticated.
This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.
Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, routes that drive JIRA operations via the raw header names must use the CamelJira* names (for example CamelJiraIssueKey) instead of the old values. For deployments that cannot upgrade immediately, strip the camel-jira control headers from any untrusted ingress before the jira: producer (for example removing the IssueKey, ProjectKey, IssueTransitionId and related headers at the start of the route), and set the required JIRA operation parameters from a trusted source.

Improper Input Validation, Unintended Proxy or Intermediary ('Confused Deputy') vulnerability in Apache Camel DAPR component.
The camel-dapr Dapr Pub/Sub consumer (DaprPubSubConsumer) copied two fields from each inbound CloudEvent - its Pub/Sub component name and its topic - into the CamelDaprPubSubName and CamelDaprTopic Exchange headers. These two headers are producer-direction routing headers: when the route republishes through a Dapr producer, DaprConfigurationOptionsProxy reads them back and prefers them over the destination configured on the endpoint. As a result, in a route that consumes from one Dapr Pub/Sub topic and republishes to another (for example from('dapr-pubsub:p:t').to('dapr-pubsub:p:other')), an actor able to publish a message to the subscribed topic could set the CloudEvent's pub/sub-name and topic to values of their choosing and cause the re-published message to be delivered to an arbitrary Dapr Pub/Sub component and topic instead of the configured destination - redirecting or exfiltrating the message and bypassing the route's intended routing and any topic-level access controls in the underlying broker. Exploitation requires the ability to publish to the topic the route subscribes to; no other authentication or user interaction is needed.
This issue affects Apache Camel: from 4.12.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.
Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. For deployments that cannot upgrade immediately, remove the CamelDaprPubSubName and CamelDaprTopic headers from the Exchange between the Dapr consumer and any Dapr producer in the route (for example removeHeaders('CamelDaprPubSubName', 'CamelDaprTopic')), and restrict who can publish to the subscribed Dapr Pub/Sub topic so that only trusted producers can send to it.

Improper Input Validation, Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in Apache Camel IRC component.
The camel-irc producer chooses the destination of an outgoing IRC message from the irc.sendTo Exchange header (the constant IrcConstants.IRC_SEND_TO, value irc.sendTo); when that header is present it overrides the channel list configured on the endpoint, and the message is sent only to the specified destination. This and the component's other control headers (irc.target, irc.messageType, irc.user.*, irc.num, irc.value) used plain, non-Camel-prefixed values. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into an irc: producer, any HTTP client could therefore set the irc.sendTo header and redirect a message that the route intended for a configured channel to an arbitrary IRC channel or user - exfiltrating the message content to an attacker-chosen nickname, leaking it into a public channel, or delivering messages that appear to come from the bot. No credentials are required when the bridging consumer is unauthenticated.
This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.

After upgrading, routes that set IRC headers via the raw header names must use the CamelIrc* names (for example CamelIrcSendTo) instead of the old irc.* values. For deployments that cannot upgrade immediately, strip the irc.* headers from any untrusted ingress before the irc: producer (for example removeHeaders('irc.*') at the start of the route), and set the IRC destination from a trusted source.

Improper Input Validation, Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in Apache Camel Kafka Component.
The camel-kafka producer can override its configured target topic at runtime from the kafka.OVERRIDE_TOPIC Exchange header: KafkaProducer.evaluateTopic() returns the header value in preference to the topic configured on the endpoint. The control-header constants in KafkaConstants (for example OVERRIDE_TOPIC = kafka.OVERRIDE_TOPIC, OVERRIDE_TIMESTAMP = kafka.OVERRIDE_TIMESTAMP, PARTITION_KEY = kafka.PARTITION_KEY) used plain, non-Camel-prefixed values. camel-kafka's own KafkaHeaderFilterStrategy does filter the kafka.* namespace, but only on the Kafka-to-Exchange serialization boundary (reading Kafka record headers into the Exchange, and writing Exchange headers into a Kafka record); it does not apply to headers that arrive from an upstream consumer in a multi-component route. The upstream HTTP consumer uses HttpHeaderFilterStrategy, which blocks only the Camel / camel namespace, so a kafka.* header passes through unfiltered. As a result, in a route that bridges an HTTP consumer (for example platform-http) into a kafka: producer, any HTTP client could set the kafka.OVERRIDE_TOPIC header and cause the message to be published to an arbitrary Kafka topic instead of the configured one - redirecting it to a sensitive internal topic, or injecting attacker-crafted messages into a topic consumed by a critical downstream service. The related kafka.OVERRIDE_TIMESTAMP and kafka.PARTITION_KEY headers could likewise be injected to backdate messages or target specific partitions. No credentials are required when the bridging consumer is unauthenticated.

For deployments that cannot upgrade immediately, strip the kafka.* headers from any untrusted ingress before the kafka: producer (for example removeHeaders('kafka.*') at the start of the route), and set the target topic from a trusted source.

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), Authorization Bypass Through User-Controlled Key vulnerability in Apache Camel Salesforce Component.
The camel-salesforce producer resolves its operation parameters - the SOQL query, the SOSL search, the target SObject name and id, the Apex REST URL and method, and the Apex query parameters - from Exchange message headers, reading the header in preference to the value configured on the endpoint (AbstractSalesforceProcessor.getParameter() reads the header first and uses the endpoint configuration only as a fallback). The control-header constants in SalesforceEndpointConfig (for example SOBJECT_QUERY = sObjectQuery, SOBJECT_SEARCH = sObjectSearch, SOBJECT_NAME = sObjectName, SOBJECT_ID = sObjectId, APEX_URL = apexUrl, APEX_METHOD = apexMethod, and the apexQueryParam. prefix) used plain, non-Camel-prefixed values. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a salesforce: producer, any HTTP client could therefore set these headers and override what the route intended - supplying its own SOQL query or SOSL search to read data from any SObject the connected Salesforce user can access, overriding the target SObject name and id for CRUD operations, or redirecting an Apex REST call to a different endpoint and HTTP method (including destructive methods) with injected query parameters. All such operations run with the full permissions of the Salesforce connected (integration) user, which is typically broad. No credentials are required from the attacker when the bridging consumer is unauthenticated.
This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.
Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, routes that set Salesforce operation parameters via the raw header names must use the CamelSalesforce* names (for example CamelSalesforceSObjectQuery and CamelSalesforceApexUrl) instead of the old sObject* / apex* values; the endpoint-option spelling is unchanged. For deployments that cannot upgrade immediately, strip the Salesforce control headers from any untrusted ingress before the salesforce: producer (for example removeHeaders('sObject*') and removeHeaders('apex*') at the start of the route), and set the query, SObject and Apex parameters from a trusted source.
