Official Description
Stack-based buffer overflow in Firebird 2.1.3 through 2.1.5 before 18514, and 2.5.1 through 2.5.3 before 26623, on Windows allows remote attackers to execute arbitrary code via a crafted packet to TCP port 3050, related to a missing size check during extraction of a group number from CNCT information.
Technical Analysis
CVE-2013-2492 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2013-2492. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
