CVE-2015-9019

16
FAUCET Score

CVE-2015-9019 describes a weakness in libxslt versions 1.1.29 and earlier, where the EXSLT math.random function lacked proper random seed initialization, leading to predictable outputs. This medium-severity vulnerability (CVSS 5.3) is network-exploitable with low attack complexity, potentially allowing an attacker to infer information (C:L) but without impacting integrity or availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this issue.
