A vulnerability, which was classified as problematic, was found in JoeyBling bootplus up to 247d5f6c209be1a5cf10cd0fa18e1d8cc63cf55d. Affected is the function qrCode of the file src/main/java/io/github/controller/QrCodeController.java. The manipulation of the argument w/h leads to resource consumption. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. This product is using a rolling release to provide continuous delivery. Therefore, no version details for affected nor updated releases are available.
With a CVSS score of 6.9, this vulnerability is classified as medium severity. The risk to organizations includes potential resource exhaustion attacks that may disrupt service availability. Given that the exploit has been disclosed, organizations must act quickly to mitigate this risk.
Organizations should prioritize patching immediately. Continuous monitoring for any signs of exploitation is also advised, as attackers may leverage this vulnerability to impact services.
The lack of specific versioning for this rolling release model heightens the urgency for organizations to assess their deployment and ensure proper configurations are in place.
Vulnerability Details
The vulnerability affects the qrCode function within the JoeyBling Bootplus component, specifically in the source file located at src/main/java/io/github/controller/QrCodeController.java. The CVSS score of 6.9 indicates a medium severity level, with potential impacts on availability due to resource consumption.
This vulnerability is categorized under CWE-400 (Uncontrolled Resource Consumption) and CWE-404 (Improper Resource Shutdown or Release). The product's rolling release nature complicates the availability of specific version information for affected releases.
Technical Analysis
The root cause of this vulnerability is the improper handling of the width and height parameters in the qrCode function, allowing for resource consumption attacks. The attack vector is network-based, and the attack complexity is low, requiring no special privileges or user interaction.
The availability impact is rated as low, meaning the exploitation could lead to degraded service operations. No confidentiality or integrity impacts are present, as the attack focuses on system resources.
Risk & Impact Analysis
Risk to organizations includes potential service disruptions due to resource exhaustion, which could affect business operations. The exploit has been made public, increasing the likelihood of attack attempts. Organizations should assess their exposure and implement necessary controls to mitigate risks.
The urgency for remediation is classified as high, given the operational implications of the vulnerability and the potential for exploitation by malicious actors.
