CVE-2022-45688 is a high-severity vulnerability affecting Hutool's JSON library, specifically in the XML.toJSONObject component. This vulnerability allows attackers to exploit a stack overflow condition, leading to a Denial of Service (DoS) attack through crafted JSON or XML data. With a CVSS score of 7.5, this vulnerability is classified as high severity, indicating significant risk to affected systems.
This vulnerability allows attackers to leverage a stack overflow, which can lead to service disruptions. The exploit can be executed over the network with low complexity, requiring no privileges or user interaction. Given its nature, organizations using affected versions of Hutool JSON should be aware of the potential risks.
Attackers may leverage this vulnerability to overwhelm the service, causing it to crash or become unresponsive. Organizations should prioritize patching this vulnerability immediately to mitigate the risks associated with Denial of Service attacks.
As of now, the exploitation status remains high, with known exploits available. Immediate action is necessary to protect systems from potential exploitation.
Vulnerability Details
The official description of CVE-2022-45688 indicates that a stack overflow in the XML.toJSONObject component of hutool-json v5.8.10 allows attackers to cause a Denial of Service (DoS) via crafted JSON or XML data. The vulnerability is classified under CWE-787.
The CVSS score for this vulnerability is 7.5, with the following metrics: attack vector is NETWORK, attack complexity is LOW, privileges required are NONE, user interaction is NONE, and the availability impact is HIGH.
Affected products include hutool version 5.8.10 and json-java versions prior to 20230227. This vulnerability was published on December 13, 2022.
Technical Analysis
The root cause of this vulnerability is a failure to adequately handle certain input data formats, leading to a stack overflow. The attack vector is primarily network-based, allowing attackers to send maliciously crafted JSON or XML data to the vulnerable component.
The attack complexity is low, meaning that attackers do not need significant skill or resources to exploit this vulnerability. Importantly, this vulnerability does not require any privileges or user interaction, which lowers the barrier for exploitation.
The potential impacts are significant, as successful exploitation could lead to service outages, affecting the availability of applications relying on this library.
Risk & Impact Analysis
Risk to organizations includes service disruption due to Denial of Service attacks, which can result in lost revenue, customer dissatisfaction, and damage to reputation. Given the ease of exploitation and the high impact of the vulnerability, organizations should assess their risk exposure.
The availability impact is rated high, which indicates that services may become completely unavailable if this vulnerability is exploited. Organizations should prioritize patching immediately.
With the increasing frequency of such vulnerabilities being targeted in the wild, it is crucial for organizations to remain vigilant and apply necessary security measures promptly.
