漏洞描述
Zimbra Collaboration Suite (ZCS) before version 10.1.20 is vulnerable to OS command injection in the SNMP notification processing due to improper input sanitization. According to the NVD, when SNMP notifications are enabled and the zimbra-snmp package is installed, an unauthenticated attacker can inject arbitrary commands using crafted SMTP requests that result in malicious log entries. The swatchdog service monitors the log, and upon matching a pattern, passes the log content to zmsnmptrapd, which unsafely uses the Perl backtick operator to execute commands. This can ultimately allow remote attackers to execute arbitrary operating system commands as the zimbra user. Active exploitation of this vulnerability has been observed in the wild, as confirmed by CERT Polska and CISA.
