CVE-2025-24882 is classified as a medium-severity vulnerability affecting regclient, a Docker and OCI Registry Client implemented in Go. This vulnerability allows a malicious registry to return an altered digest for a pinned manifest without detection. The implications of this vulnerability could lead to unauthorized access or manipulation of Docker images, which is a critical concern for organizations relying on containerization for their applications.
The CVSS score for this vulnerability is 5.2, indicating a medium level of severity. The attack vector is classified as network-based, requiring low complexity, and necessitating high privileges and user interaction. Organizations need to be aware of the potential risks associated with this vulnerability and act accordingly to protect their environments.
Published on January 29, 2025, this vulnerability is currently marked as deferred, meaning that it may not be actively exploitable at this time. Despite this status, organizations should remain vigilant and prioritize remediation to mitigate any potential risks.
Organizations should consider upgrading to version 0.7.1 or later of regclient, where this vulnerability has been addressed. The need for prompt action remains critical, as vulnerabilities in container management can have significant implications for overall security posture.
Risk to organizations includes unauthorized access to container images and potential manipulation of application environments, making this vulnerability a noteworthy concern for security teams.
Organizations should prioritize patching immediately.
The vulnerabilities associated with regclient are categorized under CWE-20 (Improper Input Validation) and CWE-345 (Insufficient Verification of Data Authenticity). These weaknesses highlight the importance of proper validation mechanisms in software that interacts with external registries.
In conclusion, CVE-2025-24882 presents a medium-risk issue that requires immediate attention from organizations utilizing regclient. Ensuring systems are updated to the latest version is essential for maintaining a secure environment.
Vulnerability Details
The official description of CVE-2025-24882 states that regclient is a Docker and OCI Registry Client in Go. A malicious registry could return a different digest for a pinned manifest without detection. This vulnerability is fixed in version 0.7.1.
The CVSS score for this vulnerability is 5.2, which indicates a medium severity level. The vulnerability classification falls under CWE-20 and CWE-345, highlighting issues with input validation and data authenticity.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper validation mechanisms in regclient when interacting with registries. Attackers can exploit this flaw by manipulating the manifest digests returned by a malicious registry.
The attack vector is network-based, requiring low complexity. It necessitates high privileges for the attacker and user interaction, making it somewhat challenging to exploit without proper access.
The vulnerability has a confidentiality impact rated as low, while the integrity impact is rated as high. This means that while unauthorized access to information may be limited, the potential for altering data is significant.
Availability impact is none, which indicates that the vulnerability does not affect the availability of the system.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-24882 is considerable, especially for organizations leveraging container technologies. The ability of a malicious actor to alter manifest digests presents a real threat that can lead to significant operational disruption and compromise.
Organizations must recognize that the integrity of container images is paramount. If an attacker can manipulate the images that an application depends on, the potential for unauthorized access and exploitation increases significantly.
Given the CVSS score of 5.2, organizations should address this vulnerability as a priority in their patch cycle. While it is currently not flagged as actively exploited, the potential for misuse makes it critical to act swiftly.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects regclient versions prior to 0.7.1. Organizations utilizing earlier versions should upgrade to mitigate this risk.
Mitigation & Remediation
Organizations should prioritize upgrading to the fixed version 0.7.1 of regclient. If immediate patching is not feasible, consider implementing network controls to restrict access to potentially malicious registries.
Additionally, employing rigorous monitoring practices can help detect any anomalous behavior related to registry interactions. Organizations may also benefit from reviewing their security posture regarding container management to ensure robust validation mechanisms are in place.
For more detailed guidance on secure practices, organizations can refer to the comprehensive resource on application security assessment.
Detection Guidance
Organizations should monitor logs for indications of unusual registry requests or digest verifications. Behavioral anomalies in the interactions with Docker registries could also signal attempts to exploit this vulnerability.
System changes, particularly those involving image pulls and manifests, should be closely observed to ensure integrity and authenticity.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2025-24882 reflects ongoing challenges in the security of container management systems. As container adoption continues to rise, vulnerabilities like this can expose organizations to severe risks if not promptly addressed.
