Juniper: >> Junos Os Evolved >> 22.4 Security Vulnerabilities
This is a similar, but different vulnerability than the issue reported as CVE-2024-39549.
A double-free vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This double free of memory is causing an rpd crash, leading to a Denial of Service (DoS).
This issue affects:
Junos OS: * from 22.4 before 22.4R3-S4.
Junos OS Evolved: * from 22.4 before 22.4R3-S4-EVO.

This issue requires a BGP session to be established.
This issue can propagate and multiply through multiple ASes until reaching vulnerable devices.
This issue affects iBGP and eBGP.
This issue affects IPv4 and IPv6.
An indicator of compromise may be the presence of malformed update messages in a neighboring AS which is unaffected by this issue:
For example, by issuing the command on the neighboring device:
show log messages
Reviewing for similar messages from devices within proximity to each other may indicate this malformed packet is propagating:
rpd[<pid>]: Received malformed update from <IP address> (External AS <AS#>)
and
rpd[<pid>]: Malformed Attribute

A Missing Release of Memory after Effective Lifetime vulnerability in the Juniper Tunnel Driver (jtd) of Juniper Networks Junos OS Evolved allows an unauthenticated network-based attacker to cause Denial of Service.
Receipt of specifically malformed IPv6 packets, destined to the device, causes kernel memory to not be freed, resulting in memory exhaustion leading to a system crash and Denial of Service (DoS). Continuous receipt and processing of these packets will continue to exhaust kernel memory, creating a sustained Denial of Service (DoS) condition.
This issue only affects systems configured with IPv6.
This issue affects Junos OS Evolved:
* from 22.4-EVO before 22.4R3-S5-EVO,
* from 23.2-EVO before 23.2R2-S2-EVO,

An Allocation of Resources Without Limits or Throttling vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved allows an authenticated, network-based attacker to cause an FPC crash leading to a Denial of Service (DoS).When specific SNMP GET operations or specific low-priviledged CLI commands are executed, a GUID resource leak will occur, eventually leading to exhaustion and resulting in FPCs to hang. Affected FPCs need to be manually restarted to recover.
GUID exhaustion will trigger a syslog message like one of the following:
evo-pfemand[<pid>]: get_next_guid: Ran out of Guid Space ...
evo-aftmand-zx[<pid>]: get_next_guid: Ran out of Guid Space ...
The leak can be monitored by running the following command and taking note of the values in the rightmost column labeled Guids:
user@host> show platform application-info allocations app evo-pfemand/evo-pfemand
In case one or more of these values are constantly increasing the leak is happening.
This issue affects Junos OS Evolved:
* All versions before 21.4R3-S7-EVO,
* 22.1 versions before 22.1R3-S6-EVO,
* 22.2 versions before 22.2R3-EVO,
* 22.3 versions before 22.3R3-EVO,
* 22.4 versions before 22.4R2-EVO.
Please note that this issue is similar to, but different from CVE-2024-47508 and CVE-2024-47509.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause an integrity impact to the downstream devices.
When a peer sends a BGP update message which contains the aggregator attribute with an ASN value of zero (0), rpd accepts and propagates this attribute, which can cause issues for downstream BGP peers receiving this.
This issue affects:
Junos OS:
* All versions before 21.4R3-S6,
* 22.2 versions before 22.2R3-S3,
* 22.4 versions before 22.4R3;

An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS).
In specific cases the state of TCP sessions that are terminated is not cleared, which over time leads to an exhaustion of resources, preventing new connections to the control plane from being established.
A continuously increasing number of connections shown by:
user@host > show system connections
is indicative of the problem. To recover the respective RE needs to be restarted manually.
This issue only affects IPv4 but does not affect IPv6.
This issue only affects TCP sessions established in-band (over an interface on an FPC) but not out-of-band (over the management ethernet port on the routing-engine).
This issue affects Junos OS Evolved:
* All versions before 21.4R3-S9-EVO,
* 22.2 versions before 22.2R3-S4-EVO,
* 22.4 version before 22.4R3-S3-EVO,

An Unimplemented or Unsupported Feature in UI vulnerability in the CLI of Juniper Networks Junos OS Evolved on QFX5000 Series allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).
Several configuration statements meant to enforce limits on MAC learning and moves can be configured but do not take effect. This can lead to control plane overload situations which will severely impact the ability of the device to processes legitimate traffic.
This issue affects Junos OS Evolved on QFX5000 Series:
* All versions before 21.4R3-S8-EVO,
* 22.2-EVO versions before 22.2R3-S5-EVO,
