CVE 설명
Sensitive data unnecessarily returned from authenticated API
Information Disclosure in API in Replicated Replicated Classic versions prior to 2.53.1 on all platforms allows authenticated users with Admin Console access to retrieve sensitive data, including application secrets, via accessing container definitions with environment variables through the Admin Console API on port 8800. This CVE was originally reserved in 2021 and later publicly disclosed by Replicated on their website on 21 October 2021. However, it mistakenly remained in the Reserved But Public (RBP) status with the CVE Numbering Authority (CNA). Please note that this product reached its end of life on 31 December 2024. Publishing this CVE with the CNA was required to comply with CNA rules, despite the fact that the issue was disclosed and fixed four years ago, and the affected product is no longer supported as of 2024. Summary of VulnerabilityThis advisory discloses a low severity security vulnerability in the versions of Replicated Classic listed above (“Affected Replicated Classic Versions”) DescriptionReplicated Classic versions prior to 2.53.1 have an authenticated API from the Replicated Admin Console that may expose sensitive data including application secrets, depending on how the application manifests are written. A user with valid credentials and access to the Admin Console port (8800) on the Replicated Classic server can retrieve container definitions including environment variables which may contain passwords and other secrets depending on how the application is configured. This data is shared over authenticated sessions to the Admin Console only, and was never displayed or used in the application processing. To remediate this issue, we removed the sensitive data from the API, sending only the data to the Admin Console that was needed. TimelineThis issue was discovered during a security review on 16 September 2021. Patched versions were released on 23 September 2021. This advisory was published on 21 October 2021. The CVE Numbering Authority (CNA) notified Replicated on 23 January 2025 that the CVE was still in Reserved But Public (RBP) status. Upon discovering the oversight in updating the status to published with the CNA, Replicated submitted the updated report on the same day, 23 January 2025.CVE 정보

Base: Exploitabilty MetricsThe Exploitability metrics reflect the characteristics of the thing that is vulnerable, which we refer to formally as the vulnerable component. Attack Vector This metric reflects the context by which vulnerability exploitation is possible. Network The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). Attack Complexity This metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability. Low Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component. Privileges Required This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability. High The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable component allowing access to component-wide settings and files. User Interaction This metric captures the requirement for a human user, other than the attacker, to participate in the successful compromise of the vulnerable component. None The vulnerable system can be exploited without interaction from any user. Base: Scope MetricsThe Scope metric captures whether a vulnerability in one vulnerable component impacts resources in components beyond its security scope. Scope Formally, a security authority is a mechanism (e.g., an application, an operating system, firmware, a sandbox environment) that defines and enforces access control in terms of how certain subjects/actors (e.g., human users, processes) can access certain restricted objects/resources (e.g., files, CPU, memory) in a controlled manner. All the subjects and objects under the jurisdiction of a single security authority are considered to be under one security scope. If a vulnerability in a vulnerable component can affect a component which is in a different security scope than the vulnerable component, a Scope change occurs. Intuitively, whenever the impact of a vulnerability breaches a security/trust boundary and impacts components outside the security scope in which vulnerable component resides, a Scope change occurs. Unchanged An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority. Base: Impact MetricsThe Impact metrics capture the effects of a successfully exploited vulnerability on the component that suffers the worst outcome that is most directly and predictably associated with the attack. Analysts should constrain impacts to a reasonable, final outcome which they are confident an attacker is able to achieve. Confidentiality Impact This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability. High There is a total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server. Integrity Impact This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information. None There is no loss of integrity within the impacted component. Availability Impact This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability. None There is no impact to availability within the impacted component. Temporal MetricsThe Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence in the description of a vulnerability. Environmental MetricsThese metrics enable the analyst to customize the CVSS score depending on the importance of the affected IT asset to a user’s organization, measured in terms of Confidentiality, Integrity, and Availability. |
