CVE-2025-59518
Description
A OS command injection found in lemonldap-ng that can occur in the Safe jail. It does not Localize _ during rule evaluation. Thus, an administrator who can edit a rule evaluated by the Safe jail can execute commands on the server.
Statement
This is a Important vulnerability because it breaks the Safe jail’s sandboxing by allowing OS command injection via the Perl _ variable. An admin can exploit this to execute arbitrary commands on the server, leading to full system compromise—far beyond a typical configuration flaw.
Mitigation
As a temporary mitigation strictly limit access to the admin interface, enforce strong authentication, and audit existing rules for suspicious code. Avoid using dynamic or complex expressions in rules until the system is fully patched.

Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
