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

The CVE-2025-20678 vulnerability is a significant flaw in the IMS service that, if exploited, could lead to a system crash due to incorrect error handling. This vulnerability is particularly dangerous as the user interaction is not required for its exploitation and no additional execution privileges are needed. This can lead to a potential system compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-20678
\nSeverity: High (7.5 CVSS)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

IMS Service | All versions prior to patch MOLY01394606<\/p>\n

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

An attacker could exploit this vulnerability by setting up a rogue base station and persuading a UE (User Equipment) to connect to it. Once connected, the rogue base station would send a series of malformed packets to the IMS service triggering an incorrect error handling, which could ultimately lead to a system crash.<\/p>\n

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

Here is a conceptual example of the rogue base station sending a malformed packet to trigger the vulnerability:<\/p>\n

POST \/IMS_Service\/endpoint HTTP\/1.1\nHost: rogueBaseStation.com\nContent-Type: application\/json\n{ \"malicious_payload\": \"malformed_packet_triggering_incorrect_error_handling\" }<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
The best way to mitigate this vulnerability is by applying the vendor patch with Patch ID: MOLY01394606. In cases where applying the patch is not immediately possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary solution. However, it’s important to note that these are not permanent fixes and the patch should be applied as soon as feasible.<\/p>\n","protected":false},"excerpt":{"rendered":"
