CVE-2022-45693 affects the Jettison library, specifically versions prior to 1.5.2. The vulnerability is categorized as a Denial of Service (DoS) risk, primarily due to a stack overflow triggered by the map parameter. This vulnerability allows attackers to send specially crafted strings that could lead to a DoS condition, making the service unavailable.
The CVSS score for this vulnerability is 7.5, indicating a high severity level. The scoring reflects a network attack vector with low complexity, requiring no privileges or user interaction. The impact on availability is rated as high, which means organizations relying on Jettison should be particularly concerned.
Considering the potential for service disruption, organizations using vulnerable versions of Jettison must take immediate action. The urgency for defenders to patch this vulnerability cannot be overstated, as it can lead to significant downtime and operational impact.
Currently, there is no known public exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and monitor for any developments regarding this vulnerability.
Vulnerability Details
The official description states: 'Jettison before v1.5.2 was discovered to contain a stack overflow via the map parameter. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted string.' The vulnerability is classified under CWE-787, which relates to improper control of the generation of code ('Code Injection').
The CVSS version is 3.1, with the vector string being: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. The key metrics indicate a network attack vector, low attack complexity, no privileges required, and high availability impact.
The vulnerability affects Jettison versions before 1.5.2. It is also relevant for systems running Debian Linux versions 10.0 and 11.0, which utilize the Jettison library.
Technical Analysis
The root cause of this vulnerability lies in a stack overflow that occurs when the map parameter is improperly handled. The attack vector is network-based, allowing an attacker to exploit the vulnerability remotely without needing physical access to the system.
Attack complexity is classified as low, meaning that the vulnerability can be exploited with minimal effort. No special privileges or user interaction are required, which increases the risk for organizations.
The impacts of this vulnerability include high availability impact, indicating that successful exploitation could lead to a complete service outage. Conversely, there is no impact on confidentiality or integrity, as the vulnerability does not expose sensitive information or alter data.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-45693 reflects the potential for significant operational disruptions. Organizations utilizing Jettison in critical services or applications may face substantial downtime if this vulnerability is exploited.
The blast radius of this vulnerability could affect any service relying on the Jettison library, leading to widespread service interruptions across applications. Given its high CVSS score, organizations must treat this vulnerability with urgency and prioritize remediation efforts.
The urgency assessment indicates that organizations should prioritize patching immediately. With the potential for exploitation leading to Denial of Service, timely remediation is vital.
