Canonical Juju up to 3.5.3 JUJU_CONTEXT_ID weak credentials

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Canonical Juju up to 2.9.50/3.1.9/3.3.6/3.4.5/3.5.3. It has been rated as problematic. This issue affects an unknown code block. The manipulation of the argument JUJU_CONTEXT_ID with an unknown input leads to a weak credentials vulnerability. Using CWE to declare the problem leads to CWE-1391. The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

JUJU_CONTEXT_ID is a predictable authentication secret. On a Juju machine (non-Kubernetes) or Juju charm container (on Kubernetes), an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJU_CONTEXT_ID value. This gives the unprivileged user access to the same information and tools as the Juju charm.

The weakness was presented by Harry Pidcock as GHSA-mh98-763h-m9v4. The advisory is shared at github.com. The identification of this vulnerability is CVE-2024-7558 since 08/06/2024. The exploitation is known to be easy. An attack has to be approached locally. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 210390 (SUSE SLES15 / openSUSE 15 Security Update : govulncheck-vulndb (SUSE-SU-2024:3911-1)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 2.9.51, 3.1.10, 3.3.7, 3.4.6 or 3.5.4 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (210390). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
