Detailsinfo

A vulnerability was found in IBM DataPower Gateways up to 7.2.0.0 and classified as critical. Affected by this issue is some unknown functionality of the component GatewayScript Decryption API/JWE Decrypt. The manipulation with an unknown input leads to a information disclosure vulnerability (Padding). Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The GatewayScript modules on IBM DataPower Gateways with software 7.2.0.x before 7.2.0.1, when the GatewayScript decryption API or a JWE decrypt action is enabled, do not require signed ciphertext data, which makes it easier for remote attackers to obtain plaintext data via a padding-oracle attack.

The weakness was presented 11/08/2015 (Website). The advisory is shared for download at www-01.ibm.com. This vulnerability is handled as CVE-2015-7412 since 09/29/2015. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

Upgrading to version 7.2.0.1 eliminates this vulnerability.
