CyberRota Analysis
AI-GeneratedThe vulnerability exists in BBOT's unarchive module, which fails to properly handle symlink entries in zip and 7z archives that contain a DOS-attribute prefix, allowing attackers to plant symlinks in the extraction directory. While the impact is limited to the creation of the symlink itself—without writing the target file—hosts utilizing legacy versions of p7zip should prioritize this issue to mitigate potential exploitation risks. Organizations still using outdated p7zip builds are particularly at risk and should take immediate action to update their software.

Original NVD Description
BBOT's unarchive module rejects archives containing symlink entries before extraction, but for zip and 7z archives it failed to detect symlinks whose listing carries a DOS-attribute prefix before the unix mode, as produced by legacy versions of p7zip. Such an archive, downloaded and extracted during a scan (for example via filedownload), bypassed the guard and caused an attacker-controlled symlink to be written into the extraction directory. The effect is limited to planting the symlink (its target is not written through), and only hosts using such a legacy p7zip build are affected; current mainline 7-Zip is not.
