CVE-2025-5139

26
FAUCET Score

CVE-2025-5139 is a critical command injection vulnerability affecting Qualitor versions 8.20 and 8.24, specifically within the Office 365-type Connection Handler component. This flaw allows remote attackers to execute arbitrary commands by manipulating the 'nmconexao' argument in the 'testaConexaoOffice365.php' file. While the attack complexity is high and exploitation is difficult, successful exploitation could lead to full compromise (confidentiality, integrity, and availability). Although public exploit details exist, there is no evidence of active exploitation, Metasploit modules, or significant community discussion, and it is not on the KEV catalog. Upgrading to Qualitor 8.20.56 or 8.24.31 remediates this issue.
