Description

Apache HTTP Server 2.2.x through 2.2.21 does not properly restrict header information during construction of Bad Request (aka 400) error documents, which allows remote attackers to obtain the values of HTTPOnly cookies via vectors involving a (1) long or (2) malformed header in conjunction with crafted web script.

Affected Apache versions (up to 2.0.21).

Remediation

Upgrade Apache 2.x to the latest version. Apache 2.2.22 is the first version that fixed this issue.

References

Fixed in Apache httpd 2.2.22
