Details Upon connecting to Cluster Manager (TCP port 5500), EoD Client sends 4 bytes: x01 x01 x00 x00, in turn CM responds with 4 bytes, negotiating the version of the protocol to use. Response from current CM version is: x0b x00 x00 x00. This triggers SSL handshake (similar to STARTSSL mechanism), credentials are then sent in encrypted SSLv3 connection: Wireshark dump of the beginning of connection: 00000000 01 01 00 00. 00000000 0b 00 00 00. 00000004 16 03 00 00 6d 01 00 00 69 03 00 52 8d e8 02 cf.m. 00000014 88 d3 96 14 f4 a3 7c 47 f3 0d 85 57 58 d6 c9 f7.|G.WX.

Exemplary bytes sent right after the 8-bytes handshake contain user login and obfuscated password. In standard connection, the same packet is sent within SSL stream. We did not try to use Kerberos-based authentication protocol, but the attack against that will most likely be identical (instead of credentials the Kerberos ticket will be sent in the clear). Access conditions Man-in-the-middle attacker Impact Credentials disclosure, authentication bypass Proof of Concept exceed-downgrade.py script can be used to test for and exploit that vulnerability. Recommendation Do not allow servers to downgrade a protocol in EoD Client communication. Always require that the credentials are sent in encrypted channel. More info • CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') - • Man in the Middle vulnerability (CVE-2013-6807) Summary If communication between EoD Client and Cluster Manager can be intercepted and tampered with (e.g. By using ARP poisoning/DNS hijacking/rogue access point), communication over SSL channel can be man-in-the-middled due to using anonymous SSL ciphers. Details Current version of EoD client when connecting to server side components, establishes encrypted SSL connection (with the exception of connecting to EoD Proxy, for which SSL encryption is optional and turned off by default). In SSL ClientHello message EoD client advertises several anonymous ciphers. In their default configuration EoD servers choose one of advertised anonymous SSL ciphers for encryption SSL_DH_anon_WITH_AES_256_CBC_SHA. $ sudo ssldump -d -i eth1 tcp port 5500 New TCP connection #1: [redacted](43426) eod.opentext.com(5500) 0.1783 (0.1783) C>S --------------------------------------------------------------- 01 01 00 00. --------------------------------------------------------------- 0.3480 (0.1697) S>C --------------------------------------------------------------- 0b 00 00 00.
