Secunia Advisory SA50363

Where:

From remote

Impact:

Cross Site Scripting, Exposure of sensitive information

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Two vulnerabilities have been reported in Apache HTTP Server, which can be exploited by malicious people to disclose certain sensitive information and conduct cross-site scripting attacks.

1) An error within the mod_proxy_ajp and mod_proxy_http modules does not properly close the connection to the back end server when handling errors. This can be exploited to disclose certain response data of a different user via specially crafted HTTP requests.

2) Certain input passed via filenames when handling untrusted uploads is not properly sanitised in the mod_negotiation module before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities are reported in versions prior to 2.4.3.


Solution:
Update to version 2.4.3.

Provided and/or discovered by:
1) Yap Sok Ann in a bug report
2) Reported by the vendor
