Organisations running the popular SAP R/3 enterprise software package risk exposing sensitive information because of a new security vulnerability, a UK government UNIRAS alert warns.

The UK's National Infrastructure Security Coordination Centre (NISCC) said the vulnerability stems from an input validation error with the SAP Internet Graphics Server sub-component of SAP R/3. The flaw creates a mechanism for hackers to launch directory traversal attacks.

NISCC rates the vulnerability, discovered by UK net security consultancy Corsaire, as high risk. Users are urged to update to version 6.40 Patch 11 or later. ®
