CVE-2023-47628: DataHub is an open-source metadata platform. DataHub Frontend's sessions are configured using Play Framework's default settings for stateless session which do not set an expiration time for a cookie. Due to this, if a session cookie were ever leaked, it would be valid forever. DataHub uses a stateless session cookie that is not invalidated on logout, it is just removed from the browser forcing the user to login again. However, if an attacker extracted a cookie from an authenticated user it would continue to be valid as there is no validation on a time window the session token is valid for due to a combination of the usage of LegacyCookiesModule from Play Framework and using default settings which do not set an expiration time. All DataHub instances prior to the patch that have removed the datahub user, but not the default policies applying to that user are affected. Users are advised to update to version 0.12.1 which addresses the issue. There are no known workarounds for this vulnerability.
The exploitability of CVE-2023-47628 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).
CVE-2023-47628 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
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-2023-47628, 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-2023-47628, 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: 0.076% (probability of exploit)
EPSS Percentile: 36.04%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 63.96% of others.
