A security flaw has been discovered in wonderwhy-er DesktopCommanderMCP up to 0.2.38. This impacts an unknown function of the file src/search-manager.ts of the component start_search. Performing a manipulation of the argument SearchResult[] results in inefficient regular expression complexity. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.2.39 will fix this issue. The patch is named 4ce845f8749b6a159b57b38dcc3357f7222a8078. It is suggested to upgrade the affected component.
Weakness
The product does not properly control the allocation and maintenance of a limited resource.
Potential Mitigations
Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
