Lifecycle Timeline
2DescriptionCVE.org
The device exposes a web interface on ports TCP/3030 and TCP/9882. This web service runs lighttpd, which implements the “SNORE” interface. This interface is affected by a stack buffer overflow vulnerability due to insecure path parsing. An attacker with access to the LAN network interface could use a specially crafted HTTP request to exploit a buffer overflow on the modem.
AnalysisAI
The device exposes a web interface on ports TCP/3030 and TCP/9882. Rated high severity (CVSS 7.7), this vulnerability is no authentication required. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. The device exposes a web interface on ports TCP/3030 and TCP/9882. This web service runs lighttpd, which implements the “SNORE” interface. This interface is affected by a stack buffer overflow vulnerability due to insecure path parsing. An attacker with access to the LAN network interface could use a specially crafted HTTP request to exploit a buffer overflow on the modem.
Affected ProductsAI
See vendor advisory for affected versions.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
