58
FAUCET Score

CVE-2013-2492 describes a stack-based buffer overflow vulnerability in Firebird versions 2.1.3 through 2.1.5 and 2.5.1 through 2.5.3 on Windows. This flaw allows remote attackers to execute arbitrary code by sending a specially crafted packet to TCP port 3050, stemming from a missing size check during group number extraction. With a CVSS score of 6.8, this vulnerability is considered medium severity, requiring no authentication but moderate attack complexity, and could lead to partial confidentiality, integrity, and availability compromise. While not listed on CISA's KEV, exploit code is publicly available via a Metasploit module, though there is no evidence of active exploitation or significant community discussion.
