On the other hand, most of time the actual user may be the victim, and it's the hacker trying to trick them into triggering the vulnerability attempting to gain admin privilege. After all, it could have been an actual exploit, not a buggy application. If 7-zip doesn't have admin privilege to begin with, whatever bug it has shouldn't have allowed it to obtain the privilege. The fix has to be the root cause that would prevent escalation even with a vulnerable application, or generic mitigation like application blacklisting, signature detection or application sandboxing. People can actively write exploits, let alone copying some vulnerable binary to trigger some known exploit. If you assume the local user is malicious, then you are totally right. This is largely true for all local privilege escalation vulnerabilities. This means that the vulnerability isn't really with 7zip at all, but with Microsoft, and there is no type of mitigation until Microsoft patches it.Depends on the threat model, whether you consider your end user trusted or not. So that means there really is no mitigation to this other than, maybe, application blacklisting?Įxpanding on the above, that means it would be far easier for someone to create a malicious dll file that explots the inherent vulnerability in Microsoft's CHM system, and then you have an exploit that doesn't depend on 7zip at all.

Could be a virus or some malware.Ĭlick check for security risks and then virus scan.Stealth006 said:The mitigation steps don't quite make sense to me, because if someone really wanted to exploit this, they would just have to download the affected 7zip executable, the affected chm file, and the specifically crafted 7z file to any system, and voila. If not, something has changed your shortcut targets, so that they are not pointing at the right. For example, if you right click the system restore icon, click properties, in the target line it should read %SystemRoot%\System32\restore\rstrui.exe and the start in line should read %HOMEDRIVE%%HOMEPATH% If it is just the shortcuts that don't work, check the target line. You could also try click start, run, type c:\windows\system32\restore\rstrui.exe, click OK.

exe file?įor example, you should get system restore to start by double clicking on the file rstrui.exe, which is in the folder c:\windows\system32\restore (hidden file and folder, so make sure you can see those). When you say that you get an error message when you open an app, do you mean when you click its shortcut? Can you start programs by double clicking on their. It would have been just my luck for something like that to happen but unfortunately, it isn't going to be so simple this time. Oh yeah, I also checked that I'm not logged on as another user. I would love to figure out this puzzle so any other advice you might offer would again be appriciated. Does that make any sense? For some reason, my Windows XP is not making the connection. It's almost as if all the programs have been deleted but most of the files are still hanging around looking for some way to be used. All of my program icons have changed to some default icon.
This is the prompt I get each time I try to open some app. Windows, however does not seem to know which program created it and therefore, can't open them. In fact, all the files I thought were missing are still there. I can locate it on the hard drive but can't open it. You don't know how much I appreciate it! Unfortunately, System Restore did not work. Or should I say, I can't get it to work.
