Overview<\/strong><\/p>\n

The cybersecurity vulnerability CVE-2025-41433 is a critical flaw that affects Message Routing virtual servers when a Session Initiation Protocol (SIP) message routing framework (MRF) application layer gateway (ALG) profile is configured. This vulnerability matters because it can potentially cause the Traffic Management Microkernel (TMM) to terminate, leading to system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-41433
\nSeverity: High (7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential for system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Message Routing Virtual Server | All versions before vendor patch<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a flaw in the SIP MRF ALG profile. When a malicious, undisclosed request is sent to the Message Routing virtual server, it can cause the TMM to terminate unexpectedly. This termination could lead to a potential system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how the vulnerability might be exploited using a SIP INVITE request:<\/p>\n

INVITE sip:target@example.com SIP\/2.0\nVia: SIP\/2.0\/UDP attacker.com;branch=z9hG4bKnashds8\nTo: \nFrom: \"Attacker\" ;tag=1928301774\nCall-ID: a84b4c76e66710\nCSeq: 314159 INVITE\nContact: \nContent-Type: application\/sdp\nContent-Length: ...\nv=0\no=user1 53655765 2353687637 IN IP4 attacker.com\ns=-\nc=IN IP4 target.example.com\nt=0 0\nm=audio 6000 RTP\/AVP 0\na=rtpmap:0 PCMU\/8000<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, apply the vendor patch as soon as it becomes available. In the meantime, use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
