Sid:
2549

--
Summary:
This event is generated when an attempt is made to exploit a vulnerability associated with the web interface support for the HP JetAdmin printer.

--
Impact:
A successful attack may allow a sensitive system file to be overwritten.

--
Detailed Information:
The HP Web JetAdmin provides a web interface for the administration of the HP Web JetAdmin printer.  A vulnerability is present that allows an existing file on the server to be overwritten. This problem exists because the script /plugins/framework/script/tree.xms does not sanitize the value supplied to the parameter WriteToFile, permitting a directory traversal from the web root
directory to any file. An attacker can supply the data to write to the specified file.

--
Affected Systems:
HP Web JetAdmin 7.2.

--
Attack Scenarios:
An attacker can overwrite a sensitive system file using the WriteToFile parameter and supplying the data to write to the file. 

--
Ease of Attack:
Simple. 

--
False Positives:
None Known.

--
False Negatives:
The default HP Web JetAdmin port is 8000.  If an administrator selects a different port on which to run the web interface, no alert will be detected.  In that case, the rule should be altered to reflect the port on which the web interface runs.

--
Corrective Action:
Upgrade to the latest non-affected version of the software or apply the appropriate patch when it becomes available.
