Summary
Missing Required Cryptographic Step Leading to Sensitive Information Disclosure in TYPO3 CMS
Details

Meta

  • CVSS: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C (8.2)
  • CWE-325, CWE-20, CWE-200, CWE-502

Problem

It has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code (HMAC-SHA1) and can lead to various attack chains as described below.

  • TYPO3-CORE-SA-2020-007, CVE-2020-15099: Potential Privilege Escalation
    • the database server used for a TYPO3 installation must be accessible for an attacker (either via internet or shared hosting network)
    • CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C (7.5, high)
  • TYPO3-CORE-SA-2016-013, CVE-2016-5091: Insecure Deserialization & Remote Code Execution
    • an attacker must have access to at least one Extbase plugin or module action in a TYPO3 installation
    • CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C (9.1, critical)

The overall severity of this vulnerability is high (8.2) based on mentioned attack chains and the requirement of having a valid backend user session (authenticated).

Solution

Update to TYPO3 versions 9.5.20 or 10.4.6 that fix the problem described.
