CVE-2009-0130

19
FAUCET Score

CVE-2009-0130 describes a potential vulnerability in Erlang's lib/crypto/c_src/crypto_drv.c, where an insufficient check of the OpenSSL DSA_do_verify function's return value could allow remote attackers to bypass SSL/TLS certificate chain validation through a malformed signature. This vulnerability is rated as HIGH severity (CVSS 7.5), indicating it can be exploited remotely with low complexity to impact integrity, though a package maintainer disputes its validity due to existing checks. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely recognized or exploited.
