Cisco Bug: CSCsz04690 - SSL Cert Header behavior may allow spoofing of trusted client
Feb 22, 2017
- Cisco CSS 11000 Series Content Services Switches
Known Affected Releases
Symptom: A reported spoofing vulnerability in the enforcement of HTTP certificate headers by researcher George D. Gal of Virtual Security Research LLC. This is documented at the following IntelliShield alert: * http://tools.cisco.com/security/center/viewAlert.x?alertId=20807 Conditions: The CSS does not look for and remove any of the headers that may be inserted as part of the http-header command, specifically "ssl-server X http-header client-cert". If someone were to insert these headers prior to encryption before they arrived at the CSS and such they were there after decryption, someone could impersonate a different client.
