Описание
Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to execute scripts in
directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI.
Users are recommended to upgrade to version 2.4.60, which fixes this issue.
Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag "UnsafeAllow3F" is specified.
A flaw was found in the mod_rewrite module of httpd. Due to a substitution encoding issue, specially crafted requests may allow an attacker to execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant only to be executed as CGI.
Отчет
This issue only affects configurations with unsafe rules used in the RewriteRule directive. Also, to exploit this flaw, an attacker must be able to upload files to the server. For these reasons, this flaw was rated with an important and not critical severity. Additionally, this flaw requires mod_rewrite to be loaded and used. This module can be disabled if its functionality is not needed. Red Hat Enterprise Linux 6 is not affected by this vulnerability because the vulnerable code was introduced in a newer version of httpd.
Меры по смягчению последствий
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
