CVE-2009-4326

14
FAUCET Score

CVE-2009-4326 describes a vulnerability in the RAND scalar function within the Common Code Infrastructure component of IBM DB2 versions 9.5 (before FP5) and 9.7 (before FP1), specifically when the Database Partitioning Feature (DPF) is enabled. This flaw causes the RAND function to generate predictable, "repeating" return values. Rated with a CVSS score of 4.3 (Medium), this vulnerability has a network attack vector and medium attack complexity, potentially allowing attackers to bypass randomization-based protection mechanisms by predicting these values, leading to a partial compromise of confidentiality. There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. The vulnerability has received minimal community discussion or media coverage, indicating a low level of public attention.
