CVE-2021-42840
Last modified
CVE-2021-42840 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. SuiteCRM before 7.11.19 allows remote code execution via the system settings Log File Name setting. In certain circumstances involving admin account takeover, logger_file_name can refer to an attacker-controlled PHP file under the web root, because only the all-lowercase PHP file extensions were blocked. EPSS estimates a 58.95% chance of exploitation in the next 30 days.
