Cisco Security Notice
Apache HTTP Server mod_rewrite Log File Manipulation Vulnerability
http://tools.cisco.com/security/center/content/CiscoSecurityNotice/CVE-2013-1862
CVE ID: CVE-2013-1862
Release Date: 2013 August 22 16:07 UTC (GMT)
Last Updated: 2013 August 26 11:21 UTC (GMT)
Summary
A vulnerability in the do_rewritelog() function of Apache HTTP Server
could allow an unauthenticated, remote attacker to gain access to
sensitive information.
The vulnerability is due to improper handling of certain escape sequences
by the affected software. An unauthenticated, remote attacker could
exploit this vulnerability by sending a crafted HTTP request to the
targeted device. Processing the crafted request could allow certain escape
sequences to be written to the log file. If an attacker views these
sequences in the log file with a terminal emulator, the attacker could
execute arbitrary commands on the targeted system.
