CVE-2014-2913: Nagios Remote Plugin Executor

High severity, CVSS 7.5. EPSS: 15.3% chance of exploitation in the next 30 days.

Incomplete blacklist vulnerability in nrpe.c in Nagios Remote Plugin Executor (NRPE) 2.15 and earlier allows remote attackers to execute arbitrary commands via a newline character in the -a option to libexec/check_nrpe. NOTE: this issue is disputed by multiple parties. It has been reported that the vendor allows newlines as "expected behavior." Also, this issue can only occur when the administrator enables the "dont_blame_nrpe" option in nrpe.conf despite the "HIGH security risk" warning within the comments

Affected products

• Nagios Remote Plugin Executor: up to and including 2.15
• Opensuse Opensuse: version 11.4 only; version 12.3 only; version 13.1 only
