CVE: CVE-2024-36052

Vulnerability Type: Improper Input Validation

CWE: [[CWE-116]], [[CWE-74]], [[CWE-707]]

Sources: VulDB, RARLAB Explaination ANSI Escape Injection Vulnerability in WinRAR

Issue Summary

A vulnerability has been discovered in RARLAB WinRAR versions up to 6.x on Windows. This issue, classified under CVE-2024-36052, involves the improper handling of ANSI escape sequences, which can lead to manipulated screen output. The vulnerability allows remote attackers to exploit this flaw without authentication, although user interaction is necessary for successful exploitation.

Technical Key Findings

The vulnerability stems from the ANSI Escape Sequence Handler within WinRAR. When a specially crafted ZIP archive containing a file with ANSI escape sequences in its name is extracted using WinRAR, the application fails to properly handle the escape sequences. Improper encoding or escaping of data results in the manipulation of screen output. This can be abused by embedding ANSI escape sequences in archive files, which when viewed by the user, can alter the output displayed in the terminal or command prompt.

Vulnerable Products

• WinRAR versions up to 6.x on Windows.

Impact Assessment

Exploiting this vulnerability can lead to the spoofing of screen outputs, potentially misleading users or administrators about the state of their system or actions being performed. This can compromise the integrity of information presented on the screen, leading to potential security breaches.

Patches or Workaround

Upgrading to WinRAR version 7.00 eliminates this vulnerability. Users are strongly advised to update to the latest version to mitigate this risk.
