CVE-2026-57874: CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in GeoVision Inc. GV-LPCLPC2011/2211
An unauthenticated buffer overflow vulnerability exists in IEEE8021x_upload.cgi in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when parsing filename values in multipart upload data. A remote attacker may exploit this vulnerability by sending a crafted upload request with overly long input, causing memory corruption and resulting in a denial of service.
AI Analysis
Technical Summary
This vulnerability is a classic buffer overflow (CWE-120) in the IEEE8021x_upload.cgi script of GeoVision GV-LPC2011 and GV-LPC2211 devices, specifically in version 1.12 and earlier. The flaw arises from inadequate validation of the size of filename inputs in multipart upload data, allowing an unauthenticated attacker to send a specially crafted upload request with an excessively long filename. This leads to memory corruption and results in a denial of service condition. The vulnerability is remotely exploitable without authentication. No vendor advisory or patch information is currently available, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation results in denial of service due to memory corruption caused by buffer overflow. There is no indication of confidentiality or integrity impact. The attack requires no privileges or user interaction and can be performed remotely over the network.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to the affected upload functionality or network segment to trusted users only to reduce exposure.
