Submit #24625: CVE-2021-35052 - Remote Code Execution in WinRAR
| Titel | CVE-2021-35052 - Remote Code Execution in WinRAR |
|---|---|
| Beschreibung | A remote code execution vulnerability existed in an old and free trial version of WinRAR, according to infosec firm Positive Technologies. While a vuln in version 5.7 of WinRAR may not seem like an immediate threat given that version was first released two years ago and has been superseded since, simple shareware/free-to-use software has a habit of being used long after its due date. The vuln, tracked as CVE-2021-35052, has since been patched. Users should check their installed versions of WinRAR and update if it isn't v 6.02 or later, though the practicality of the attack seems limited unless your device or network is first compromised by other means. WinRAR offers users a free trial licence before gently nagging users to buy a licence. Its most closely associated file compression format, the .rar archive, is not opened by Windows Explorer – so WinRAR is popular among those who have to work with the format, or those who simply had to download a .rar archive once and needed a utility to open it.
