CVE-2013-6839

28
FAUCET Score

CVE-2013-6839 describes a SQL injection vulnerability in InstantSoft InstantCMS versions 1.10.3 and earlier, allowing remote attackers to execute arbitrary SQL commands. This critical flaw, with a CVSS score of 7.5, stems from improper sanitization of the 'orderby' parameter in the catalog/[id] function, enabling unauthenticated attackers to compromise data confidentiality, integrity, and availability with low attack complexity. While not listed in CISA's KEV catalog, a public exploit (EDB-30398) for blind SQL injection exists, though there is no evidence of active exploitation, Metasploit modules, or significant community discussion or media coverage.
