Torrentflux · Torrentflux · CVE-2008-2020
**Name of the Vulnerable Software and Affected Versions**
Francisco Burzi PHP-Nuke versions 7.0 through 8.1
my123tkShop e-Commerce-Suite version 0.9.1
phpMyBitTorrent version 1.2.2
TorrentFlux version 2.3
e107 version 0.7.11
WebZE version 0.5.9
Open Media Collectors Database version 1.5.0b4
Labgab version 1.1
**Description**
The CAPTCHA implementation uses a code bg.jpg background image and the PHP `ImageString` function in a way that produces an insufficient number of different images. This allows remote attackers to pass the CAPTCHA test via an automated attack using a table of all possible image checksums and their corresponding digit strings.
**Recommendations**
For Francisco Burzi PHP-Nuke versions 7.0 through 8.1, consider implementing a more secure CAPTCHA system that produces a sufficient number of different images.
For my123tkShop e-Commerce-Suite version 0.9.1, restrict access to sensitive areas of the application until a more secure CAPTCHA system is implemented.
For phpMyBitTorrent version 1.2.2, disable the CAPTCHA test until a patch is available that addresses the issue.
For TorrentFlux version 2.3, avoid using the `ImageString` function for CAPTCHA generation until a more secure alternative is available.
For e107 version 0.7.11, consider using a different CAPTCHA implementation that is not vulnerable to automated attacks.
For WebZE version 0.5.9, restrict access to the CAPTCHA-protected areas of the application until a more secure CAPTCHA system is implemented.
For Open Media Collectors Database version 1.5.0b4, disable the CAPTCHA test until a patch is available that addresses the issue.
For Labgab version 1.1, consider implementing a more secure CAPTCHA system that produces a sufficient number of different images.
