Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, does not sign all required data in requests, which has unspecified impact, probably related to man-in-the-middle attacks that modify critical data and allow remote attackers to impersonate other users and gain privileges.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, does not use timeouts for signed requests, which allows remote attackers to impersonate other users and gain privileges via a replay attack that sends the same request.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, uses an insecure hash when signing requests, which allows remote attackers to impersonate other users and gain privileges.

Unspecified vulnerability in Services 6.x before 6.x-0.14, a module for Drupal, when key-based access is enabled, allows remote attackers to read or add keys and access unauthorized services via unspecified vectors.
