Data handling in IBM BladeCenter Switches

1) Data Handling

EUVDB-ID: #VU33638

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-7575

CWE-ID: CWE-19 - Data Handling

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Mozilla Network Security Services (NSS) before 3.20.2, as used in Mozilla Firefox before 43.0.2 and Firefox ESR 38.x before 38.5.2, does not reject MD5 signatures in Server Key Exchange messages in TLS 1.2 Handshake Protocol traffic, which makes it easier for man-in-the-middle attackers to spoof servers by triggering a collision.

Mitigation

Install update from vendor's website.

Vulnerable software versions

IBM BladeCenter 1/10Gb Uplink Ethernet Switch Module: before 6.8.24.0
