Title: CMU SNMP SNMPTRAPD Daemon Remote Format String Vulnerability
Severity: CRITICAL
Description:
CMU SNMP is a freely available implementation of SNMP (Simple Network Management Protocol). It has since been called UCD-SNMP, and then Net-SNMP.
A remote format string vulnerability affects the CMU SNMP's snmptrapd daemon. This issue is due to a failure of the application to properly sanitize user-supplied input data prior to using it in a formatted-printing function.
This issue presents itself when the snmptrapd daemon attempts to process specially crafted SNMP packets. The 'snmp_input()' function improperly includes attacker-supplied data in the format-specifier argument to a formatted printing function.
A remote attacker may leverage this issue to execute arbitrary code with superuser privileges, facilitating the complete compromise of affected computers.
It should be noted that CMU SNMP has not been actively maintained for several years.
Affected Products:
- Carnegie Mellon University CMU SNMP 3.6.0
