Vulnerability Details CVEID: CVE-2015-7575 DESCRIPTION: The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials. CVSS Base Score: 7.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N) Affected Products and Versions IBM DataPower Gateway appliances all versions through 6.0.0.17, 6.0.1.13, 7.0.0.10, 7.1.0.7. Versions 7.2.0.0 and later are not affected by this vulnerability. Remediation/Fixes Fix is available in versions 6.0.0.18, 6.0.1.14, 7.0.0.11, 7.1.0.8. Refer to APAR IT13422 for URLs to download the fix. You should verify applying this fix does not cause any compatibility issues. IBM recommends that you review your entire environment to identify other areas where you have enabled the MD5 signature hash and take appropriate mitigation and remediation actions. For DataPower customers using versions 5.x and earlier versions, IBM recommends upgrading to a fixed, supported version/release/platform of the product. Workarounds and Mitigations None.
