CVE-2019-18215: Comodo Internet Security

High severity, CVSS 7.8. EPSS: 0.6% chance of exploitation in the next 30 days.

An issue was discovered in signmgr.dll 6.5.0.819 in Comodo Internet Security through 12.0. A DLL Preloading vulnerability allows an attacker to implant an unsigned DLL named iLog.dll in a partially unprotected product directory. This DLL is then loaded into a high-privileged service before the binary signature validation logic is loaded, and might bypass some of the self-defense mechanisms.

Affected products

• Comodo Comodo Internet Security: before 12.1.0.6914 (fixed in 12.1.0.6914)
