Q1: Is WinRAR 5.01 free?

1. What is WinRAR 5.01?

Released in late 2013, WinRAR 5.01 is an updated build of the major WinRAR 5.0 architecture. It was designed to address bugs from the initial 5.0 release while introducing performance enhancements. The "full version" refers to the licensed, unrestricted edition—unlike the trial version that displays a nag screen after 40 days.

WinRAR 5.01 is renowned for:

  • Superior compression ratios for RAR and ZIP formats.
  • Faster unpacking speeds for large archives.
  • Improved encryption using AES-256.
  • Support for multi-volume archives (splitting large files into smaller parts).

3. Security & Vulnerabilities

Notable CVEs affecting WinRAR versions before 5.70 (including 5.01):

| CVE | Issue | Fixed in | |------|-------|-----------| | CVE-2018-20250 | ACE file extraction path traversal (ACE format bug) | 5.70 beta 1 | | CVE-2018-20251 | Race condition via temporary files | 5.61 | | CVE-2018-20252 | Out-of-bounds write in RAR4 recovery volumes | 5.60 |

Recommendation: Do not use 5.01 for handling untrusted archives, especially .ace, .rar, or .sfx files from unknown sources. The CVE-2018-20250 exploit (WinRAR ACE vulnerability) is weaponized and widely used in malware campaigns.

Security Context

Looking back at WinRAR 5.01, security researchers often cite this version as a turning point. Prior versions had vulnerabilities regarding absolute path traversal (CVE-2018-14768), which could allow malicious archives to write files outside the target directory when extracted.

While version 5.01 was secure for its time, it is not immune to modern vulnerabilities discovered years later. For users running legacy systems that cannot be updated to version 6.x, version 5.01 is generally considered the last stable build for Windows XP, though it should be used with caution when handling untrusted archives.
