CVE-2013-1300
win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT does not properly handle objects in memory, which allows local users to gain privileges via a crafted application, aka "Win32k Memory Allocation Vulnerability."
CVSS
- Version: 2.0
- Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
- Base score: 7.2
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 12%
- Percentile among all scored CVEs: 96
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
- Metasploit module (reliable, widely available exploit) · Windows NTUserMessageCall Win32k Kernel Pool Overflow (Schlamperei)
- Published on Exploit-DB · Microsoft Windows - NTUserMessageCall Win32k Kernel Pool Overflow 'schlamperei.x86.dll' (MS13-053) (Metasploit) (5/6/2014)
