CVE-2018-19792 (GCVE-0-2018-19792)
Vulnerability from nvd – Published: 2018-12-03 06:00 – Updated: 2024-08-05 11:44
VLAI
Summary
The server in LiteSpeed OpenLiteSpeed before 1.5.0 RC6 allows local users to cause a denial of service (buffer overflow) or possibly have unspecified other impact by creating a symlink through which the openlitespeed program can be invoked with a long command name (involving ../ characters), which is mishandled in the LshttpdMain::getServerRootFromExecutablePath function.
Severity
No CVSS data available.

CVE-2018-19792 (GCVE-0-2018-19792)
Vulnerability from cvelistv5 – Published: 2018-12-03 06:00 – Updated: 2024-08-05 11:44
VLAI
Summary
The server in LiteSpeed OpenLiteSpeed before 1.5.0 RC6 allows local users to cause a denial of service (buffer overflow) or possibly have unspecified other impact by creating a symlink through which the openlitespeed program can be invoked with a long command name (involving ../ characters), which is mishandled in the LshttpdMain::getServerRootFromExecutablePath function.
Severity
No CVSS data available.
