Security readout for executives and security teams
CVE-2018-20252 is a WinRAR memory corruption flaw in versions up to and including 5.60. A malicious archive could cause code execution as the user who opens or processes it. Business risk is highest where staff handle untrusted compressed files from email, downloads, or file exchanges. Windows workstations or servers with WinRAR 5.60 or older are the likely exposure, especially systems where users extract archives from external or untrusted sources. Treat this as a high-priority endpoint remediation issue because archive tools are common and the impact is code execution when users process malicious files. Mitigation focus: Upgrade WinRAR to a version newer than 5.60.; Check WinRAR release notes and vendor guidance for fixed versions.; Restrict handling of untrusted ACE and RAR archives where possible..
