SEH-based stack buffer overflow in Allok Video to DVD Burner 2.6.1217 License Name field
CVE-2018-25303 is a stack-based buffer overflow in Allok Video to DVD Burner 2.6.1217. The flaw is present in the application's License Name field used during registration. According to the provided content, a local attacker can trigger the vulnerability by supplying an overly long crafted string to that field, specifically described as 780 bytes of junk data followed by SEH chain pointers and shellcode. Successful exploitation overwrites the structured exception handler (SEH) chain and redirects execution to attacker-controlled payloads, resulting in arbitrary code execution in the context of the vulnerable process.
What it means and what to do now: patch path, interim mitigations, and the assume-compromise checklist.
What an attacker gets, and what they’ve been doing with it.
Successful exploitation allows arbitrary code execution on the local system in the security context of the user running Allok Video to DVD Burner. Because the issue is a stack-based overflow with SEH overwrite control, exploitation can fully compromise the affected process and may lead to complete loss of confidentiality, integrity, and availability for data accessible to that user context.
If you can’t patch tonight, do this now.
Do not use Allok Video to DVD Burner 2.6.1217 on systems where untrusted local users can interact with the application. Restrict execution to trusted users only, and prevent copy/paste or manual entry of untrusted data into the registration dialog. Application control, exploit mitigation features, and endpoint protections may reduce exploit reliability, but they do not remove the underlying flaw.
Patch, then assume compromise.
Upgrade from Allok Video to DVD Burner 2.6.1217 to a vendor-fixed version if one is available. If no patched release is available, discontinue use of the vulnerable version and replace it with a supported alternative. The vulnerable input handling in the License Name registration field should be corrected by enforcing strict bounds checking and safe memory handling for user-supplied data.
