22
FAUCET Score

CVE-2025-0276 describes an insecure Content Security Policy (CSP) vulnerability in HCL BigFix Modern Client Management (MCM) 3.3 and earlier, impacting both BigFix Mobile and BigFix Modern Client Management products. This medium-severity vulnerability (CVSS 6.1) allows an attacker to trick users into performing unintended actions due to insufficient restrictions on script and content sources. While the attack vector is network-based and low complexity, it requires user interaction and could lead to low impact on confidentiality and integrity. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
