Adobe ColdFusion versions 2023.5 (and earlier) and 2021.11 (and earlier) are affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an unauthenticated attacker is able to convince a victim to visit a URL referencing a vulnerable page, malicious JavaScript content may be executed within the context of the victim's browser. This vulnerability allows attackers to potentially steal sensitive information and perform actions on behalf of users.
The CVSS score for this vulnerability is 6.1, classified as medium severity. The attack vector is network-based, which means attackers can exploit this vulnerability remotely without physical access to the vulnerable system. The exploit complexity is low, and it requires user interaction, making awareness and education about this vulnerability crucial for users.
Risk to organizations includes potential data theft and unauthorized actions performed in the context of a user's session. Organizations should prioritize patching immediately to mitigate this risk, especially since this vulnerability could be exploited through social engineering tactics.
As of now, there is no known public exploit or proof of concept available. However, the high exploitability score indicates that this vulnerability could be leveraged by attackers if not addressed promptly.
Vulnerability Details
This vulnerability is classified under CWE-79, indicating a reflected Cross-Site Scripting (XSS) issue. It affects Adobe ColdFusion, specifically versions 2023.5 and 2021.11 and earlier. The vulnerability was published on November 17, 2023, and has been modified since its initial disclosure.
Technical Analysis
The root cause of this vulnerability lies in improper validation of user input, allowing attackers to inject malicious scripts into web pages that are then executed in the browsers of unsuspecting users. The attack vector is primarily network-based, requiring the victim to interact with a malicious URL.
The complexity of exploiting this vulnerability is low, as it does not require advanced skills or privileged access. However, it does necessitate some form of user interaction, such as clicking a link. The confidentiality and integrity impacts are classified as low, while there is no availability impact.
Risk & Impact Analysis
Organizations utilizing affected versions of Adobe ColdFusion face significant risks due to the potential for data theft and unauthorized actions. The blast radius could be extensive, affecting all users who might be tricked into visiting a malicious link. Given the medium severity and the associated exploitability, organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Adobe ColdFusion prior to the vendor patch are affected. Specific vulnerable versions include 2023.5 and 2021.11, along with all earlier updates.
Mitigation & Remediation
Organizations should prioritize patching to the latest version of Adobe ColdFusion to mitigate this vulnerability. If an immediate patch is not available, consider implementing web application firewalls (WAFs) to filter out potentially malicious requests and educate users about the risks of clicking on untrusted links. For more comprehensive security measures, organizations can engage in penetration testing to identify further vulnerabilities.
Detection Guidance
Monitoring logs for indications of unauthorized script execution and behavioral anomalies is crucial. Look for unusual network traffic patterns or log entries that suggest exploitation attempts. Additionally, organizations should keep an eye on user reports of unexpected behavior.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in its potential to expose organizations to data breaches and loss of user trust. As XSS vulnerabilities are commonly exploited, the patterns of such vulnerabilities indicate a need for robust input validation and user education. Security teams should leverage this incident to strengthen their application security practices and consider regular vulnerability management programs to mitigate similar risks in the future. Furthermore, organizations should invest in penetration testing methodology to continuously assess their security posture.
Lastly, organizations should not underestimate the importance of fostering a culture of security awareness among employees, as they are the first line of defense against social engineering attacks.
