CVE-2020-15530 (GCVE-0-2020-15530)

Vulnerability from nvd – Published: 2020-07-05 00:31 – Updated: 2024-08-04 13:15

Summary

An issue was discovered in Valve Steam Client 2.10.91.91. The installer allows local users to gain NT AUTHORITY\SYSTEM privileges because some parts of %PROGRAMFILES(X86)%\Steam and/or %COMMONPROGRAMFILES(X86)%\Steam have weak permissions during a critical time window. An attacker can make this time window arbitrarily long by using opportunistic locks.

Severity

No CVSS data available.

CVE-2020-15530 (GCVE-0-2020-15530)

Vulnerability from cvelistv5 – Published: 2020-07-05 00:31 – Updated: 2024-08-04 13:15

Summary

An issue was discovered in Valve Steam Client 2.10.91.91. The installer allows local users to gain NT AUTHORITY\SYSTEM privileges because some parts of %PROGRAMFILES(X86)%\Steam and/or %COMMONPROGRAMFILES(X86)%\Steam have weak permissions during a critical time window. An attacker can make this time window arbitrarily long by using opportunistic locks.

Severity

No CVSS data available.
