CVE-2021-43269 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. In Code42 app before 8.8.0, eval injection allows an attacker to change a device’s proxy configuration to use a malicious proxy auto-config (PAC) file, leading to arbitrary code execution. This affects Incydr Basic, Advanced, and Gov F1; CrashPlan Cloud; and CrashPlan for Small Business. EPSS estimates a 1.34% chance of exploitation in the next 30 days.
