Description

A vulnerability classified as problematic was found in chaitak-gorai Blogbook up to 92f5cf90f8a7e6566b576fe0952e14e1c6736513. This vulnerability affects unknown code of the file /search.php of the component GET Parameter Handler. The manipulation of the argument Search leads to denial of service. The exploit has been disclosed to the public and may be used. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The vendor was contacted early about this disclosure but did not respond in any way.

Technical Analysis

CVE-2025-5404 is a medium severity vulnerability affecting the chaitak-gorai Blogbook software, specifically in the /search.php component that handles GET parameters. The vulnerability arises from improper handling of the 'Search' argument, which can be manipulated by an attacker to trigger a denial of service (DoS) condition. This DoS likely results from resource exhaustion or application crash caused by malformed or malicious input to the search functionality. The product uses a rolling release model, which complicates version tracking and patch management, and no official patch or updated release addressing this vulnerability has been made available. The vendor was contacted but did not respond, leaving users without vendor-supported remediation. The CVSS 4.0 base score of 5.3 reflects a medium severity, with the vector indicating that the attack requires network access (AV:A), no privileges (PR:N), no user interaction (UI:N), and results in a loss of availability (VA:L) without impacting confidentiality or integrity. Public disclosure of the exploit exists, but no known active exploitation in the wild has been reported. The vulnerability is limited to the GET parameter handling in the search feature, which is a common entry point for web-based attacks. Given the lack of vendor response and patch, the risk remains until mitigations are applied by users or maintainers.

Potential Impact

For European organizations using chaitak-gorai Blogbook, this vulnerability could lead to denial of service conditions, rendering the affected web application or service unavailable. This can disrupt business operations, degrade user experience, and potentially cause reputational damage if public-facing services are impacted. While the vulnerability does not directly compromise data confidentiality or integrity, availability loss can affect critical communication or content delivery platforms relying on Blogbook. Organizations in sectors with high availability requirements, such as media, publishing, or public information portals, may face operational risks. Additionally, the lack of vendor response and patch availability increases the window of exposure, potentially inviting attackers to exploit the vulnerability once automated tools incorporate the public exploit details. The medium severity suggests moderate impact, but the ease of exploitation without authentication and user interaction increases the likelihood of opportunistic attacks.

Mitigation Recommendations

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'Search' GET parameter in /search.php requests, focusing on abnormal input patterns or excessive request rates. 2) Implement rate limiting and request throttling on the search endpoint to reduce the risk of resource exhaustion. 3) Conduct code review and apply temporary input validation or sanitization on the search parameter if source code access is available, rejecting suspicious or malformed inputs. 4) Monitor application logs and network traffic for unusual spikes or patterns indicative of exploitation attempts. 5) Consider isolating or temporarily disabling the search functionality if it is not critical, until a patch or update is available. 6) Engage with the open-source community or maintainers to track any unofficial patches or forks addressing this issue. 7) Maintain up-to-date backups and incident response plans to quickly recover from potential service disruptions.
