CVSS

Base: None Impact: Exploitability:

CWE CWE-294 CAPEC
 * Man in the Middle Attack
   This type of attack targets the communication between two components
   (typically client and server). The attacker places himself in the
   communication channel between the two components. Whenever one component
   attempts to communicate with the other (data flow, authentication challenges,
   etc.), the data first goes to the attacker, who has the opportunity to
   observe or alter it, and it is then passed on to the other component as if it
   was never observed. This interposition is transparent leaving the two
   compromised components unaware of the potential corruption or leakage of
   their communications. The potential for Man-in-the-Middle attacks yields an
   implicit lack of trust in communication or identify between two components.
   MITM attacks differ from sniffing attacks since they often modify the
   communications prior to delivering it to the intended recipient. These
   attacks also differ from interception attacks since they may forward the
   sender's original unmodified data, after copying it, instead of keeping it
   for themselves.
 * Session Sidejacking
   Session sidejacking takes advantage of an unencrypted communication channel
   between a victim and target system. The attacker sniffs traffic on a network
   looking for session tokens in unencrypted traffic. Once a session token is
   captured, the attacker performs malicious actions by using the stolen token
   with the targeted application to impersonate the victim. This attack is a
   specific method of session hijacking, which is exploiting a valid session
   token to gain unauthorized access to a target system or information. Other
   methods to perform a session hijacking are session fixation, cross-site
   scripting, or compromising a user or server machine and stealing the session
   token.
 * Reusing Session IDs (aka Session Replay)
   This attack targets the reuse of valid session ID to spoof the target system
   in order to gain privileges. The attacker tries to reuse a stolen session ID
   used previously during a transaction to perform spoofing and session
   hijacking. Another name for this type of attack is Session Replay.
