CVE-2025-23925 refers to an improper neutralization of input during web page generation, specifically a Cross-site Scripting (XSS) vulnerability within the jp2112 Feedburner Optin Form plugin. This vulnerability allows stored XSS, which can be exploited by an attacker to inject malicious scripts into the web application.
The CVSS score for this vulnerability is 6.5, categorizing it as medium severity. This score indicates a moderate level of risk to organizations, particularly those that utilize the affected plugin version (<= 0.2.8). Given its potential impact, organizations should address this issue promptly.
Risk to organizations includes the possibility of unauthorized access to sensitive information, manipulation of user sessions, and the execution of malicious code. Attackers may leverage this vulnerability to perform actions on behalf of users without their consent, which can lead to significant reputational and operational damage.
Currently, there are no known exploits associated with this vulnerability, indicating that while it poses a risk, it has not been actively weaponized in the wild. However, organizations should still prioritize patching immediately to mitigate any potential exploitation.
To summarize, the urgency for defenders is high, and organizations should implement the necessary updates to the jp2112 Feedburner Optin Form plugin to safeguard against this vulnerability.
Vulnerability Details
The official description of this vulnerability states that it allows improper neutralization of input during web page generation, specifically affecting the jp2112 Feedburner Optin Form plugin. The vulnerability is classified under CWE-79, which pertains to improper input validation.
The CVSS vector string is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, reflecting a network attack vector, low attack complexity, and requiring low privileges and user interaction. The impacts on confidentiality, integrity, and availability are all rated as low.
This vulnerability affects all versions of the Feedburner Optin Form plugin up to and including version 0.2.8. The issue was published on January 16, 2025.
Technical Analysis
The root cause of this vulnerability lies in the plugin's failure to adequately sanitize user input before rendering it on web pages. This oversight allows attackers to inject malicious scripts, which can be executed in the context of other users' browsers.
The attack vector is primarily network-based, meaning that an attacker can exploit this vulnerability remotely without needing physical access to the target system. With low attack complexity, even less skilled attackers could potentially exploit this issue.
Privileges required for exploitation are low, as attackers do not need privileged access to exploit the vulnerability. However, user interaction is required, meaning that users must trigger the XSS by interacting with the compromised content.
The confidentiality, integrity, and availability impacts are rated as low, indicating that while the risks are present, the potential for severe damage may be limited without additional factors.
Risk & Impact Analysis
In the real-world deployment of the Feedburner Optin Form plugin, the risk involves the potential for attackers to inject scripts that can manipulate user session data or perform actions on behalf of users. The impact of such exploitation can vary, leading to unauthorized access to sensitive information, data leakage, and degraded user trust.
Organizations utilizing this plugin should be particularly vigilant, as the blast radius can extend beyond the initial target, affecting all users interacting with the compromised system. The urgency assessment based on the CVSS score suggests that organizations should address this vulnerability in their priority patch cycle.
Given that this vulnerability is not actively being exploited in the wild, it provides a window of opportunity for organizations to remediate without immediate threat. However, proactive measures should still be taken to ensure this vulnerability does not become a target in the future.
