Security Vulnerabilities
Yamcs is a mission control framework. Prior to 5.12.7, a server-side code injection vulnerability existed in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory, which dynamically compiled and evaluated user-controlled algorithm text through the Janino compiler without enforcing a secure sandbox, so an authenticated user with the ChangeMissionDatabase privilege could override an existing algorithm's text via the mission database REST API and inject Java code (for example using java.lang.Runtime) to achieve remote code execution on the underlying host operating system. This issue is fixed in versions 5.12.7 and 5.13.0, which disable algorithm editing by default.

Yamcs is a mission control framework. Prior to 5.12.7, the authentication endpoint POST /auth/token in yamcs-core, handled by yamcs-core/src/main/java/org/yamcs/http/auth/AuthHandler.java, lacked any rate limiting, account lockout, or failed-attempt throttling, so an unauthenticated remote attacker could perform unlimited password-guessing attempts against any user account, significantly increasing the risk of successful brute-force attacks. This issue is fixed in versions 5.12.7 and 5.13.0.

Yamcs is a mission control framework. Prior to 5.12.7, the IAM API endpoints listUsers, getUser, listGroups, and getGroup in yamcs-core did not enforce the required SystemPrivilege.ControlAccess check in yamcs-core/src/main/java/org/yamcs/http/api/IamApi.java, so any authenticated user, even one with low or no privileges, could enumerate all user accounts in the system including their usernames, superuser status, and group memberships. This issue is fixed in versions 5.12.7 and 5.13.0.

HCL DFXAnalytics is affected by an Account Takeover via Response Manipulation vulnerability. A remote attacker can intercept and alter the contents of the server's HTTP responses before they reach the client application, allowing them to manipulate the authentication or authorization logic to bypass controls and gain unauthorized access to targeted user accounts.

HCL DFXAnalytics is affected by a Deprecated Protocol vulnerability due to the use of TLS 1.0 and TLS 1.1. These legacy protocols contain numerous cryptographic design flaws that expose data to interception and decryption. To remediate this risk, the application must disable all support for TLS 1.0 and TLS 1.1, and exclusively enable support for secure protocols, specifically TLS 1.2 and TLS 1.3.

HCL DFXAnalytics is affected by a Buffer Overflow vulnerability that can lead to a Denial of Service (DoS). The application fails to properly validate input sizes, allowing an attacker to pass an excessive amount of information into a memory container, which can cause the system to crash or become unresponsive. To mitigate this flaw, comprehensive input length checks must be implemented and enforced on both the client and server sides.

HCL DFXAnalytics is affected by an Internal File Path Disclosure vulnerability. The application dashboard inadvertently leaks sensitive information regarding its internal file structure and directory paths through unhandled error messages, system logs, or debugging output, which could allow a remote attacker to map the underlying server environment and identify targets for further exploitation.

HCL DFXAnalytics is affected by a Missing HTTP Strict-Transport-Security Header vulnerability. The application fails to implement the HTTP Strict Transport Security (HSTS) policy within its responses, which could allow a remote attacker to downgrade the communication channel to an unencrypted connection (HTTP) and conduct man-in-the-middle (MitM) attacks. To remediate this, the application must include the "Strict-Transport-Security" header in all web application responses.

HCL DFXAnalytics is affected by a Missing Secure Attribute in Encrypted Session (SSL) Cookie vulnerability. The application fails to set the "secure" attribute on session cookies generated during authentication, which could allow a remote attacker to intercept network traffic and capture sensitive cookies, session tokens, or credentials sent in cleartext over unencrypted channels.

HCL DFXAnalytics is affected by a Login Replay Attack vulnerability. The application allows a remote attacker to intercept, delay, or fraudulently retransmit valid authentication data to achieve unauthorized access. To mitigate this risk, the application must implement a mechanism to include timestamps with every message, ensuring that messages exceeding a specific age threshold are automatically rejected by the recipient system.
