1.0.1
A cross-site scripting (XSS) vulnerability exists in My-Blog versions 1.0.0 and earlier. This flaw stems from improper handling of data within the /admin/tags/save file, allowing attackers to inject malicious scripts. Successful exploitation could lead to session hijacking or defacement of the blog. The vulnerability has been publicly disclosed and a patch is available in version 1.0.1.
The XSS vulnerability in My-Blog allows an attacker to inject arbitrary JavaScript code into the application. This code will then be executed in the context of a user's browser when they visit a compromised page. An attacker could leverage this to steal session cookies, redirect users to malicious websites, or deface the blog's content. The impact is particularly severe if the blog is used for sensitive information or has a large user base, as a successful attack could affect many users simultaneously. This type of XSS is often used as a stepping stone for further attacks, such as phishing or malware distribution.
This vulnerability has been publicly disclosed, increasing the likelihood of exploitation. While the CVSS score is LOW, the ease of exploitation and potential impact warrant attention. No known active campaigns targeting this specific vulnerability have been reported as of the publication date, but the availability of a public proof-of-concept suggests that exploitation is possible. The vulnerability was published on 2025-08-18.
Blog administrators and users of My-Blog are at risk. Specifically, those using older, unpatched versions (1.0.0 and earlier) are vulnerable. Shared hosting environments running My-Blog are also at increased risk due to the potential for cross-tenant exploitation.
• generic web: Use curl to test the /admin/tags/save endpoint with a simple XSS payload (e.g., <script>alert(1)</script>).
curl -X POST -d '<script>alert(1)</script>' http://your-blog-url/admin/tags/save• generic web: Examine access and error logs for suspicious requests to /admin/tags/save containing XSS payloads.
• generic web: Check response headers for the presence of XSS payloads after submitting data to /admin/tags/save.

The primary mitigation for CVE-2025-9101 is to upgrade My-Blog to version 1.0.1 or later, which contains the fix. If upgrading is not immediately feasible, consider implementing input validation and output encoding on the /admin/tags/save endpoint to sanitize user-supplied data. Web application firewalls (WAFs) configured to detect and block XSS payloads can also provide a temporary layer of protection. Review and restrict access to the /admin/tags/save endpoint to authorized personnel only.
如果存在，请将 My-Blog 更新到 1.0.0 之后的版本以修复跨站脚本 (XSS) 漏洞。如果不存在更新，请考虑禁用或删除 Tag Handler 组件。作为临时措施，您可以在文件 /admin/tags/save 中实施输入验证和转义规则，以降低恶意代码注入的风险。
