Summary

A flaw was found in environment-modules. A local attacker can place a maliciously named modulefile in a location visible to the victim's MODULEPATH. When the victim uses Bash completion for module or ml commands, the malicious module name containing shell metacharacters is evaluated as a command.

Risk Assessment

Arbitrary command execution may occur in the completing user's shell, impacting the confidentiality, integrity, and availability of their environment.

Recommendation

Update environment-modules to a patched version. Until then, avoid Bash completion for module/ml commands and control the contents of directories in MODULEPATH.

Original NVD description (English source)

A flaw was found in environment-modules. A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability.
