Description

Several stack-based buffer overflow vulnerabilities exist in the DetranCLI command parsing functionality of Siretta QUARTZ-GOLD G5.0.1.5-210720-141020. A specially-crafted network packet can lead to arbitrary command execution. An attacker can send a sequence of requests to trigger these vulnerabilities.This buffer overflow is in the function that manages the 'bandwidth WORD dlrate <1-9999> dlceil <1-9999> ulrate <1-9999> ulceil <1-9999> priority (highest|high|normal|low|lowest)' command template.
