Title: CA20090429-01: CA ARCserve Backup Apache HTTP Server Multiple Vulnerabilities

CA Advisory Date: 2009-04-29

Reported By:

Impact: A remote attacker can cause a denial of service, or a local attacker can exploit a buffer overflow to gain apache privileges.

Summary: CA ARCserve Backup on Solaris, Tru64, HP-UX, and AIX contains multiple vulnerabilities in the Apache HTTP Server version as shipped with ARCserve Backup. CA has issued updates that contain version 2.0.63 of the Apache HTTP Server to address the vulnerabilities. Refer to the References section for a list of resolved issues by CVE identifier.

Mitigating Factors: None


Severity: CA has given these vulnerabilities a Medium risk rating.

Affected Platforms:

Status and Recommendation:
CA has issued the following patches to address the vulnerabilities.

CA ARCserve Backup r11.5 Solaris:
RO06786

CA ARCserve Backup r11.5 Tru64:
RO06788

CA ARCserve Backup r11.5 HP-UX:
RO06789

CA ARCserve Backup r11.5 AIX:
RO06791


How to determine if you are affected:

1. From the command line, run the following to print the version of the Apache HTTP Server included with ARCserve Backup:

      $BAB_HOME/httpd/httpd -v

      Note: On HP-UX the shared library path needs to be modified prior to running the httpd command:

      SHLIB_PATH=$SHLIB_PATH:$BAB_HOME/httpd/lib
      export SHLIB_PATH

2. If the displayed version is less than 2.0.63, then the installation may be vulnerable.


Workaround:
As a workaround solution, disable the Apache HTTP Server with the "stopgui" command. To re-enable the server, run "startgui".

Stopping the Apache HTTP Server will prevent the ARCserve user from performing GUI operations. Most of the operations provided by the GUI can be accomplished via the command line.

Alternatively, restrict remote network access to reduce exposure.
