CVE-2025-43992 affects Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.3.0.0. This vulnerability allows an authentication bypass by assumed-immutable data in Geo replication. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access to data in transit.
With a CVSS score of 5.6, classified as medium severity, this vulnerability poses a risk to organizations as it opens the door for unauthorized access to sensitive information. Given the nature of the vulnerability, attackers may leverage this weakness to intercept data during transmission.
Organizations should prioritize patching immediately. The urgency stems from the potential for exploitation, which could lead to data breaches if the vulnerability is not addressed soon.
Although currently listed as undergoing analysis, the lack of confirmed public exploits means that organizations have a timely opportunity to remediate this issue before it can be actively exploited.
Organizations should remain vigilant and continuously monitor for any related developments.
Vulnerability Details
Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.3.0.0 contain an authentication bypass by assumed-immutable data vulnerability in Geo replication. An unauthenticated attacker with remote access could exploit this vulnerability, leading to unauthorized access to data in transit.
The CVSS score for this vulnerability is 5.6, which categorizes it as medium severity. This score indicates a network attack vector with high complexity, no privileges required, and no user interaction needed for successful exploitation. The impacts on confidentiality, integrity, and availability are all rated as low.
The vulnerability classification falls under CWE-302, indicating that it is an authentication bypass issue.
Technical Analysis
The root cause of this vulnerability lies in the Geo replication functionality of Dell ECS and ObjectScale. The assumed-immutable data concept allows attackers to bypass authentication mechanisms, granting them unauthorized access to sensitive data in transit. The attack vector is categorized as network-based, requiring high complexity to execute, with no privileges or user interaction necessary.
The confidentiality, integrity, and availability impacts are low, indicating that while data may be accessed, it does not result in a complete compromise of the system. However, the potential for unauthorized access to sensitive information remains a significant risk.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to data in transit, which could lead to significant data breaches and compliance violations. The blast radius potential is considerable, especially for organizations that handle sensitive information. Given the medium severity of CVSS, organizations should address this vulnerability in their priority patch cycle.
The urgency for remediation is medium, as while there are currently no public exploits confirmed, the potential for an attack exists. Organizations must be proactive in assessing their exposure and implementing necessary patches.
