Detailsinfo

A vulnerability has been found in Jasper httpdx 1.4/1.4.5/1.4.6/1.4.6b/1.5 (Programming Tool Software) and classified as very critical. Affected by this vulnerability is the function tolog. The manipulation with an unknown input leads to a format string vulnerability. The CWE definition for the vulnerability is CWE-134. The product uses a function that accepts a format string as an argument, but the format string originates from an external source. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple format string vulnerabilities in the tolog function in httpdx 1.4, 1.4.5, 1.4.6, 1.4.6b, and 1.5 allow (1) remote attackers to execute arbitrary code via format string specifiers in a GET request to the HTTP server component when logging is enabled, and allow (2) remote authenticated users to execute arbitrary code via format string specifiers in a PWD command to the FTP server component.
