Revive Adserver Security Advisory REVIVE-SA-2017-001

Vulnerability 1 – Deserialization of Untrusted Data

  • CVE-ID: TBA
  • CWE-ID: CWE-502
  • CVSSv3 Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C
  • CVSSv3 Base Score: 9.8
  • CVSSv3 Temporal Score: 8.5

Description

HackerOne user Nicolas Grégoire – Agarri has reported that Revive Adserver was unserializing untrusted data submitted via cookies in the delivery scripts. An attacker could use such vector to either perform generic RCE attacks (e.g. when a vulnerable PHP version is being used) or, potentially, application-specific attacks.

Vulnerability 2 – Session Fixation

  • CVE-ID: TBA
  • CWE-ID: CWE-384
  • CVSSv3 Vector: CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C
  • CVSSv3 Base Score: 5.9
  • CVSSv3 Temporal Score: 5.2

Description

HackerOne user pavanw3b has reported that Revive Adserver wasn’t properly invalidating the current session when setting a new password via the forgot password mechanism. This could allow attackers having access to the session ID to keep the authenticated session alive.

  • CVE-ID: TBA
  • CWE-ID: CWE-79
  • CVSSv3 Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C

  • CVSSv3 Temporal Score: 3.7

Description

HackerOne user pavanw3b has reported that Revive Adserver was vulnerable to a persistent XSS attack: an authenticated user could set their own email address to a specifically crafted string which was then displayed without proper escaping in the context of other users (e.g. the administrator user), giving them an opportunity to steal a session with elevated privileges.
