Detailsinfo

A vulnerability classified as critical has been found in RRWO File::Rotate::Simple up to 0.3.x. This affects the function rotate. The manipulation with an unknown input leads to a permission vulnerability. CWE is classifying the issue as CWE-275. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

File::Rotate::Simple versions before 0.4.0 for Perl create the target of dangling symlinks when rotating files. When the file to be rotated is a symbolic link to a missing file, and the touch option is enabled, then the rotate method assumes that the file is absent (since the existence check is against the target), and does not rotate it. But it touches the file, which creates the target. An attacker that has the ability to create the symlink can use this to create an arbitrary file with permissions of the process rotating the files (which may be different from the process that normally writes to the log file that is being rotated). Note that the touch option is disabled by default.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-17435 since 07/25/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1222 for this issue.
