CVE-2024-47554 is a medium-severity vulnerability classified as an uncontrolled resource consumption issue in Apache Commons IO. This vulnerability allows the org.apache.commons.io.input.XmlStreamReader class to excessively consume CPU resources when processing maliciously crafted input. The CVSS score for this vulnerability is 4.3, indicating a moderate level of risk.
Organizations utilizing affected versions of Apache Commons IO should urgently address this issue, as failure to do so may lead to performance degradation or denial of service scenarios in their applications. The vulnerability impacts all versions of Apache Commons IO prior to 2.14.0. Users are recommended to upgrade to version 2.14.0 or later to mitigate this risk.
The vulnerability was published on October 3, 2024, and is currently classified as analyzed. With known exploits available, organizations must act swiftly to protect their systems.
Given the nature of this vulnerability and its potential impact on system resources, organizations should prioritize patching immediately. The risk to organizations includes potential service disruption and resource exhaustion.
Vulnerability Details
The vulnerability allows excessive consumption of CPU resources due to the processing of maliciously crafted input by the XmlStreamReader class. It affects Apache Commons IO versions from 2.0 up to, but not including, 2.14.0. Users should upgrade to version 2.14.0 or later to mitigate this vulnerability.
Technical Analysis
The root cause of CVE-2024-47554 is attributed to the manner in which the XmlStreamReader processes input. When faced with specially crafted XML data, the class can enter a state that leads to excessive CPU usage. The attack vector is network-based, requiring low attack complexity. Importantly, no privileges are required to exploit this vulnerability, and user interaction is necessary to trigger the exploit by providing malicious input.
Risk & Impact Analysis
The potential blast radius of this vulnerability can affect any application relying on vulnerable versions of Apache Commons IO. Organizations must recognize that the risk to their systems includes performance degradation and possible denial of service. The urgency of addressing this issue is emphasized by its CVSS score of 4.3, placing it in the medium severity category. Given the availability of known exploits, organizations should prioritize patching in their immediate response plans.
