Q4What can hackers do? (Privileges/Data)
๐ฏ **Attacker Goal**: Disrupt service availability. ๐ซ **Privileges**: Likely requires local access or a malicious application to trigger the kernel function. ๐ฆ **Data**: No direct data exfiltration mentioned.โฆ
๐ **Threshold**: Moderate to High. ๐งฉ **Auth**: Usually requires a local user to run a malicious program or a remote vector if triggered via browser/printer spooler (common for win32k bugs).โฆ
๐ป **Public Exp**: YES! ๐ **Link**: GitHub repo `ExploitCN/CVE-2013-3660-x64-WIN7`. ๐ **Success Rate**: Claimed 100% on x64 Windows 7. ๐ Wild exploitation is possible.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**:
1. Check OS version against the list in Q3.
2. Verify if MS13-053 patch is installed.
3. Use vulnerability scanners detecting `win32k.sys` flaws.โฆ
๐ฉน **Fixed**: YES. ๐ **Patch Date**: May 2013. ๐ **Bulletin**: MS13-053. โ Microsoft released a security update to fix this kernel flaw.
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**:
