IBM DataPower Gateways 7.1, 7.2, 7.5, 7.5.1, 7.5.2, 7.6, and 7.7 and IBM MQ Appliance are vulnerable to a denial of service, caused by the improper handling of full file system. A local attacker could exploit this vulnerability to cause a denial of service. IBM X-Force ID: 145171.

IBM DataPower Gateway 7.1.0.0 - 7.1.0.23, 7.2.0.0 - 7.2.0.21, 7.5.0.0 - 7.5.0.16, 7.5.1.0 - 7.5.1.15, 7.5.2.0 - 7.5.2.15, and 7.6.0.0 - 7.6.0.8 as well as IBM DataPower Gateway CD 7.7.0.0 - 7.7.1.2 are vulnerable to a XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 144950.

IBM DataPower Gateway 7.1.0.0 - 7.1.0.23, 7.2.0.0 - 7.2.0.21, 7.5.0.0 - 7.5.0.16, 7.5.1.0 - 7.5.1.15, 7.5.2.0 - 7.5.2.15, and 7.6.0.0 - 7.6.0.8 as well as IBM DataPower Gateway CD 7.7.0.0 - 7.7.1.2 echoing of AMP management interface authorization headers exposes login credentials in browser cache. IBM X-Force ID: 144890.

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.
