Last modified

CVE-2018-25255 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. 10-Strike LANState 8.8 contains a local buffer overflow vulnerability in structured exception handling that allows local attackers to execute arbitrary code by crafting malicious LSM map files. Attackers can create a specially formatted LSM file with a payload in the ObjCaption parameter that overflows the buffer, overwrites the SEH chain, and executes shellcode when the file is opened in the application.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
