CVE-2022-23400: TALOS-2022-1465 || Cisco Talos Intelligence Group

A stack-based buffer overflow vulnerability exists in the IGXMPXMLParser::parseDelimiter functionality of Accusoft ImageGear 19.10. A specially-crafted PSD file can overflow a stack buffer, which could either lead to denial of service or, depending on the application, to an information leak. An attacker can provide a malicious file to trigger this vulnerability.

RedLine.Stealer Code Execution

RedLine looks for and loads a DLL named "wow64log.dll" in Windows\System32. Therefore, we can drop our own DLL to intercept and terminate the malware. The exploit DLL will simply display a Win32API message box and call exit(). Our RedLine exploit DLL must export the "InterlockedExchange" function or it fails with an error. We do not need to rely on a hash signature or third-party product, the malware vulnerability will do the work for us. Endpoint protection systems and or antivirus can potentially be killed prior to executing malware, but this method cannot as there's nothing to kill the DLL that just lives on disk waiting. From a defensive perspective you can add the DLLs to a specific network share containing important data as a layered approach. All basic tests were conducted successfully in a virtual machine environment.

REvil Ransom Code Execution

REvil looks for and executes DLLs in its current directory. Therefore, we can potentially hijack a vulnerable DLL to execute our own code, control and terminate the malware pre-encryption. The exploit DLL will check if the current directory is "C:\Windows\System32" and if not we grab our process ID and terminate. We do not need to rely on a hash signature or third-party product, the malware's own vulnerability will do the work for us.

Conti Ransom Code Execution

Conti looks for and executes DLLs in its current directory. Therefore, we can potentially hijack a vulnerable DLL to execute our own code and control and terminate the malware pre-encryption.

LokiLocker Ransom Code Execution

LokiLocker looks for and executes DLLs in its current directory. Therefore, we can potentially hijack a vulnerable DLL to execute our own code, control and terminate the malware pre-encryption. The exploit DLL will check if the current directory is "C:\Windows\System32" and if not we grab our process ID and terminate. We do not need to rely on a hash signature or third-party product as the malware will do the work for us. Endpoint protection systems and or antivirus can potentially be killed prior to executing malware, but this method cannot as there is nothing to kill the DLL that just lives on disk waiting.

BlackBasta Ransom Code Execution

BlackBasta looks for and loads a DLL named wow64log.dll in Windows\System32. Therefore, we can drop our own DLL to intercept and terminate the malware pre-encryption. The exploit DLL will simply display a Win32API message box and call exit(). Our BlackBasta exploit DLL must export the InterlockedExchange function or it fails with error.
