CVE-2022-25851 is a high-severity vulnerability affecting the jpeg-js package, specifically versions prior to 0.4.4. This vulnerability allows for a Denial of Service (DoS) condition where a specific piece of input causes the application to enter an infinite loop, leading to resource exhaustion. The vulnerability has been assigned a CVSS score of 7.5, indicating a high level of risk. Organizations should prioritize patching immediately.
The vulnerability is classified as having a high impact on availability, making it critical for organizations using this library to address it. The attack vector is network-based, with low complexity and no required privileges or user interaction, which increases the potential for exploitation.
As of now, there are no known exploits for this vulnerability publicly available, but the potential for future exploitation remains. Organizations using affected versions must ensure they are tracking this issue closely and implementing necessary updates to mitigate risks.
In light of the impact and exploitability of this vulnerability, organizations should address it in their priority patch cycle to avoid potential service interruptions.
Vulnerability Details
The official description of CVE-2022-25851 indicates that the package jpeg-js before version 0.4.4 is vulnerable to a Denial of Service (DoS) condition. The vulnerability allows for an infinite loop to be triggered by specific input, ultimately leading to service disruption.
The CVSS score for this vulnerability is 7.5, classified as high severity. The factors contributing to this score include an attack vector of network, low attack complexity, no required privileges, and no user interaction required. The availability impact is rated as high, meaning that the service could be significantly disrupted if exploited.
The affected product is the jpeg-js library, and the vulnerability was published on June 10, 2022. The Common Weakness Enumeration (CWE) classification for this vulnerability is CWE-835, which pertains to infinite loop vulnerabilities.
Technical Analysis
The root cause of this vulnerability lies in the handling of specific input that leads to an infinite loop within the jpeg-js library. Attackers could exploit this vulnerability over the network due to the low attack complexity, which means it can be triggered easily without sophisticated techniques.
The attack complexity is classified as low, meaning that an attacker does not need specialized knowledge to exploit this vulnerability. Furthermore, it requires no privileges to execute the attack, making it accessible to a wider range of attackers.
There is no user interaction required to trigger the vulnerability, which adds to its severity. The confidentiality, integrity, and availability impacts are assessed as none, none, and high respectively, confirming that the primary risk is service availability.
Risk & Impact Analysis
The risk to organizations includes potential service disruptions caused by the infinite loop triggered by this vulnerability. Given that the jpeg-js library is commonly used in various applications, the impact could be significant, affecting many users and services.
Organizations should assess their usage of the jpeg-js library and determine if they are using a vulnerable version. The availability impact is rated as high, indicating that exploitation could lead to substantial downtime and loss of service.
