Lifecycle Timeline
1DescriptionNVD
A stack-based buffer overflow vulnerability exists in the CMA check_udp_crc function of Garrett Metal Detectors’ iC Module CMA Version 5.0. A specially-crafted packet can lead to a stack-based buffer overflow during a call to memcpy. An attacker can send a malicious packet to trigger this vulnerability.
AnalysisAI
A stack-based buffer overflow vulnerability exists in the CMA check_udp_crc function of Garrett Metal Detectors’ iC Module CMA Version 5.0. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and 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. A stack-based buffer overflow vulnerability exists in the CMA check_udp_crc function of Garrett Metal Detectors’ iC Module CMA Version 5.0. A specially-crafted packet can lead to a stack-based buffer overflow during a call to memcpy. An attacker can send a malicious packet to trigger this vulnerability. Affected products include: Garrett Ic Module Cma. Version information: Version 5.0..
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.
