A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class. This vulnerability allows the bypassing of validation by omitting the tag ending in a less-than character. Consequently, browsers may render an invalid HTML, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.
The vulnerability has a CVSS score of 6.1, classifying it as medium severity. This score indicates that the risk to organizations includes potential unauthorized access and data manipulation through XSS attacks. Given its exploitability and the impact it may have on web applications, organizations should address this vulnerability promptly.
While there is no confirmed public exploit available, the nature of this vulnerability suggests that attackers may leverage it to manipulate web content or redirect users, posing significant risks to both users and the integrity of the application.
Organizations should prioritize patching immediately to safeguard against potential exploitation. Regular updates and vigilant monitoring are essential to maintain application security and mitigate risks associated with this vulnerability.
Vulnerability Details
The vulnerability in question is detailed in the CVE-2023-1932 record. It affects the hibernate-validator component within various Red Hat products, including CodeReady Studio and JBoss Enterprise Application Platform. The vulnerability was published on November 7, 2024, and has been classified under CWE-79, which refers to improper neutralization of input during web page generation ('Cross-site Scripting').
The attack vector for this vulnerability is categorized as NETWORK, with a low attack complexity, requiring no privileges and user interaction. The confidentiality and integrity impacts are rated as low, while there is no impact on availability. This assessment highlights the importance of addressing this vulnerability in a timely manner.
Technical Analysis
The root cause of this vulnerability is found in the validation logic of the hibernate-validator's 'isValid' method. The validation can be bypassed, allowing attackers to inject malicious HTML content or scripts into web pages. This flaw stems from a failure to properly handle specific HTML tag endings, leading to potential XSS vulnerabilities.
Given the low complexity of the attack, attackers can exploit this vulnerability remotely, without requiring any special privileges. While user interaction is necessary to trigger the vulnerability, it remains a significant security concern that could lead to unauthorized actions within the application.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is considerable. Attackers may leverage this flaw to execute malicious scripts, leading to data theft, session hijacking, or defacement of web content. The potential blast radius can vary based on how widely the affected components are utilized within an organization's infrastructure.
Organizations should assess their exposure to this vulnerability based on their usage of the affected products. Given the CVSS score of 6.1, the urgency for remediation is categorized as medium. Regular vulnerability assessments and timely patching are crucial to mitigating risks.
