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

The CVE-2025-20667 vulnerability refers to a potential information disclosure issue in modems due to improper error handling. This security flaw can lead to remote information disclosure when a User Equipment (UE) connects to a rogue base station controlled by an attacker. It is a critical issue as it does not require any additional execution privileges and can be exploited without user interaction, thereby threatening the confidentiality of affected systems.<\/p>\n

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

CVE ID: CVE-2025-20667
\nSeverity: High (CVSS: 7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Modem | All versions prior to patch MOLY01513293<\/p>\n

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

The CVE-2025-20667 exploit works by taking advantage of incorrect error handling in modems. When a UE connects to a rogue base station controlled by an attacker, the attacker can exploit this vulnerability to disclose information remotely. This vulnerability does not require any additional execution privileges, and user interaction is not needed for its exploitation.<\/p>\n

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

While the exact exploit code is not disclosed to protect systems’ security, an attacker might exploit the vulnerability in a similar way to the following conceptual example:<\/p>\n

GET \/modem\/info HTTP\/1.1\nHost: roguebase.example.com<\/code><\/pre>\n
The attacker could use this request to retrieve sensitive information from the modem, taking advantage of the incorrect error handling.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, it is advisable to apply the vendor patch with ID: MOLY01513293. In the absence of a patch, or until the patch can be applied, organizations can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Regularly monitoring network traffic for suspicious activities can also help in early detection and prevention.<\/p>\n","protected":false},"excerpt":{"rendered":"
