| EnGarde Secure Linux Security Advisory February 25, 2003 |
| http://www.engardelinux.org/ ESA-20030225-006 |
| |
| Package: WebTool |
| Summary: WebTool session ID spoofing vulnerability. |
+------------------------------------------------------------------------+
EnGarde Secure Linux is a secure distribution of Linux that
features improved access control, host and network intrusion
detection, Web based secure remote management, e-commerce, and
integrated open source security tools.
OVERVIEW
- --------
Components of the Guardian Digital WebTool are derived from the popular
Webmin package by Jamie Cameron.
Keigo Yamazaki discovered a vulnerability in miniserv.pl (the
webserver program at the core of the WebTool) which may allow an
attacker to spoof a session ID by including special metacharacters
in the BASE64 encoded string using during the authentication
process.
This may allow a remote attacker to gain full administrative
privileges over the WebTool. All users are recommended to upgrade
immediately.
SOLUTION
- --------
Users of the EnGarde Professional edition can use the Guardian Digital
Secure Network to update their systems automatically.
EnGarde Community users should upgrade to the most recent version
as outlined in this advisory. Updates may be obtained from:
ftp://ftp.engardelinux.org/pub/engarde/stable/updates/
http://ftp.engardelinux.org/pub/engarde/stable/updates/
Before upgrading the package, the machine must either:
a) be booted into a "standard" kernel; or
b) have LIDS disabled.
To disable LIDS, execute the command:
# /sbin/lidsadm -S -- -LIDS_GLOBAL
To install the updated package, execute the command:
# rpm -Uvh files
You must now update the LIDS configuration by executing the command:
# /usr/sbin/config_lids.pl
To re-enable LIDS (if it was disabled), execute the command:
# /sbin/lidsadm -S -- +LIDS_GLOBAL
To verify the signatures of the updated packages, execute the
command:
# rpm -Kv files
