CVE-2024-45042: Ory Kratos is an identity, user management and authentication system for cloud services. Prior to version 1.3.0, given a number of preconditions, the `highest_available` setting will incorrectly assume that the identity’s highest available AAL is `aal1` even though it really is `aal2`. This means that the `highest_available` configuration will act as if the user has only one factor set up, for that particular user. This means that they can call the settings and whoami endpoint without a `aal2` session, even though that should be disallowed. An attacker would need to steal or guess a valid login OTP of a user who has only OTP for login enabled and who has an incorrect `available_aal` value stored, to exploit this vulnerability. All other aspects of the session (e.g. the session’s aal) are not impacted by this issue. On the Ory Network, only 0.00066% of registered users were affected by this issue, and most of those users appeared to be test users. Their respective AAL values have since been updated and they are no longer vulnerable to this attack. Version 1.3.0 is not affected by this issue. As a workaround, those who require MFA should disable the passwordless code login method. If that is not possible, check the sessions `aal` to identify if the user has `aal1` or `aal2`.
The exploitability of CVE-2024-45042 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The exploitability of CVE-2024-45042 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2024-45042, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2024-45042, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.043% (probability of exploit)
EPSS Percentile: 12.0%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 88.0% of others.
