Description Murray McAllister 2014-04-22 02:46:11 EDT

A remote, command execution flaw was discovered in Nagios NRPE when command arguments are enabled. A remote attacker could use this flaw to execute arbitrary commands. This issue affects versions 2.15 and older.

Command arguments are disabled by default ("dont_blame_nrpe=0" in "/etc/nagios/nrpe.cfg"), and the security risk of enabling them is documented.

Some discussion about the fix is available on the oss-security list: http://seclists.org/oss-sec/2014/q2/129

Comment 1 Murray McAllister 2014-04-22 02:47:19 EDT

Created nrpe tracking bugs for this issue:

Affects: fedora-all [bug 1089879]
Affects: epel-all [bug 1089880]

Comment 4 Fedora Update System 2014-05-15 23:02:55 EDT

nrpe-2.15-2.el6 has been pushed to the Fedora EPEL 6 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 5 Todd Zullinger 2014-07-27 16:05:36 EDT

EPEL-5 remains vulnerable.  I had a few systems compromised by this over the weekend.  I rebuilt nrpe-2.15-2 on el5 to fix my systems, but an update should be pushed to prevent others from falling victim to attacks that are occurring in the wild.

Comment 6 Fedora Update System 2014-11-19 10:56:59 EST

nrpe-2.15-2.fc20 has been pushed to the Fedora 20 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 7 Fedora Update System 2014-12-06 23:35:59 EST

nrpe-2.15-2.fc19 has been pushed to the Fedora 19 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 9 Todd Zullinger 2015-08-22 22:04:10 EDT

EPEL-5 remains vulnerable to this issue.  No errata has been issued for EPEL-5, AFAIK.  Exploits have been seen in the wild as well.
