CVE-2025-3967: Improper Authorization in itwanger paicoding
A vulnerability was found in itwanger paicoding 1.0.3. It has been classified as critical. This affects an unknown part of the file /article/api/post of the component Article Handler. The manipulation of the argument articleId leads to improper authorization. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
AI Analysis
Technical Summary
CVE-2025-3967 is a vulnerability identified in version 1.0.3 of the itwanger paicoding software, specifically within the Article Handler component that processes requests to the /article/api/post endpoint. The vulnerability arises from improper authorization checks related to the manipulation of the articleId parameter. This flaw allows an attacker to remotely exploit the system by crafting requests that bypass authorization controls, potentially granting unauthorized access or modification capabilities to articles or posts managed by the application. The vulnerability does not require user interaction and can be exploited over the network without prior authentication, indicating a low barrier to exploitation. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N) reflects a medium severity score of 5.3, highlighting that while the attack complexity is low and no user interaction is needed, some level of privileges (low privileges) is required to exploit the flaw. The impact primarily affects the integrity and availability of the article data, with limited confidentiality impact. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of active exploitation. The vulnerability is critical in nature due to improper authorization but is rated medium severity because of the requirement for low privileges and limited scope of impact. No official patches or mitigation links have been published yet, which increases the urgency for organizations using this software to implement compensating controls or monitor for suspicious activity.
Potential Impact
For European organizations utilizing itwanger paicoding 1.0.3, this vulnerability poses a significant risk to the integrity and availability of content managed through the Article Handler API. Attackers could manipulate articleId parameters to alter, delete, or publish unauthorized content, potentially leading to misinformation, reputational damage, or disruption of services reliant on the affected application. Organizations in sectors such as media, publishing, education, or any that use paicoding for content management could face operational disruptions. The lack of authentication requirement for exploitation means that external attackers can attempt to exploit this vulnerability remotely, increasing the attack surface. Additionally, the public availability of exploit details may lead to automated scanning and exploitation attempts, raising the risk of widespread attacks. Confidentiality impact is limited, but integrity and availability concerns could affect trustworthiness and reliability of published information. This could also have compliance implications under European data protection regulations if content integrity is critical to regulatory requirements. The medium severity rating suggests that while the vulnerability is serious, it is not expected to cause full system compromise or data breaches without additional factors.
Mitigation Recommendations
Given the absence of official patches, European organizations should take immediate practical steps to mitigate risk: 1) Implement strict access controls and monitoring on the /article/api/post endpoint to detect and block anomalous requests manipulating articleId parameters. 2) Employ Web Application Firewalls (WAFs) with custom rules to filter unauthorized API calls targeting articleId parameters. 3) Restrict API access to trusted IP ranges or authenticated users where possible, even if the application does not enforce it by default. 4) Conduct thorough code reviews and consider temporary disabling or restricting the vulnerable API endpoint if feasible until a patch is available. 5) Monitor logs for unusual activity patterns indicative of exploitation attempts, such as repeated requests with varying articleId values from unknown sources. 6) Engage with the vendor or open-source community to obtain or accelerate the release of a security patch. 7) Educate development and security teams about the vulnerability to ensure rapid response to any incidents. These measures go beyond generic advice by focusing on immediate containment and detection strategies tailored to the vulnerability's characteristics.
