Name of the Vulnerable Software and Affected Versions Siretta QUARTZ-GOLD version G5.0.1.5-210720-141020

Description The issue concerns stack-based buffer overflow vulnerabilities in the DetranCLI command parsing functionality. A specially-crafted network packet can lead to arbitrary command execution.

Recommendations For Siretta QUARTZ-GOLD version G5.0.1.5-210720-141020, as a temporary workaround, consider restricting access to the DetranCLI command parsing functionality until a patch is available.
