This vulnerability allows allocation of resources without limits or throttling in Apache Commons Compress, specifically impacting versions from 1.21 before 1.26. The potential for resource exhaustion can lead to an OutOfMemoryError, making this a notable concern for affected systems.
With a CVSS score of 5.5, this medium-severity vulnerability should not be overlooked. Organizations utilizing affected versions are at risk of degraded performance or system failures due to resource exhaustion. Timely remediation is crucial, as attackers may leverage this flaw to disrupt service availability.
As this vulnerability is actively exploitable, organizations must prioritize patching to ensure continuity of service and protect against potential exploitation. Users are recommended to upgrade to version 1.26, which addresses this issue effectively.
Organizations should prioritize patching immediately. This step is vital to safeguarding systems against exploitation.
For further details, Apache has provided advisory information related to this vulnerability.
Vulnerability Details
This vulnerability allows allocation of resources without limits or throttling in Apache Commons Compress. This issue affects Apache Commons Compress: from 1.21 before 1.26. Users are recommended to upgrade to version 1.26, which fixes the issue.
The vulnerability is classified under CWE-770, indicating a weakness related to resource management.
The CVSS score for this vulnerability is 5.5, indicating a medium severity. The attack vector is local, with low complexity, and does not require any privileges, but does necessitate user interaction. The impact on availability is high, indicating significant potential disruption.
Technical Analysis
The root cause of this vulnerability stems from inadequate resource allocation controls in the affected versions of Apache Commons Compress. This allows an attacker with local access to exploit the flaw by providing crafted input that leads to excessive resource consumption.
The attack vector is local, meaning the attacker must have some level of access to the system where Apache Commons Compress is running. The attack complexity is low, indicating that the exploit could be executed without significant effort.
No privileges are required for the exploitation of this vulnerability, and user interaction is necessary, as the crafted input must be provided by a user.
The impact on confidentiality and integrity is none, but the availability impact is high due to the potential for resource exhaustion leading to service disruption.
Risk & Impact Analysis
Risk to organizations includes potential service disruptions due to resource exhaustion, which can lead to degraded system performance or complete outages. The blast radius is significant in environments where Apache Commons Compress is utilized extensively.
Organizations should address in priority patch cycle as the exploitation of this vulnerability can lead to severe operational impacts. The urgency is heightened by the active exploitation status, and timely remediation is essential.
