A security flaw has been discovered in CheckMAL AppCheck Pro 3.1.43.10. Affected is an unknown function in the library AppCheckD.sys of the component Kernel Mini-Filter Driver. Performing a manipulation results in uncontrolled search path. The attack requires a local approach. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
What this means
- Exposure
- Exploitable with local access to the machine, with an ordinary user account and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
