Overview<\/strong><\/p>\n

In the ever-evolving landscape of cybersecurity, new vulnerabilities continue to emerge, posing significant threats to both individual users and large-scale organizations. One such vulnerability, CVE-2025-26855, has been identified in the Joomla content management system’s Articles Calendar extension. Specifically, versions 1.0.0 to 1.0.1.0007 of the extension are susceptible to SQL injection<\/a> attacks, which can potentially lead to system compromise or data leakage. This vulnerability carries a high severity<\/a> rating, making it a critical area of focus for anyone using the affected extension.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-26855

\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise, data leakage<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Articles Calendar extension for Joomla | 1.0.0 – 1.0.1.0007<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a flaw in the Articles Calendar extension for Joomla, which fails to properly sanitize user inputs in SQL queries. This allows an attacker to inject malicious SQL code<\/a> into the application, which can then be executed by the database management system. This could potentially lead to unauthorized<\/a> access to sensitive data, manipulation of said data, or even complete control over the affected system.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a high-level conceptual example of how this type of SQL injection vulnerability<\/a> could be exploited:<\/p>\n

POST \/index.php?option=com_articlescalendar&view=articlescalendar HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nid=1 UNION SELECT 1,username,password FROM #__users<\/code><\/pre>\n
In this example, the malicious SQL code<\/a> (1 UNION SELECT 1,username,password FROM #__users) is injected into the ‘id’ parameter of the POST request. This results in the execution of an additional SQL query, which could potentially retrieve sensitive user information<\/a> from the database.<\/p>\n
Mitigation<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the vendor’s patch as soon as possible. In the absence of a patch or until one can be applied, users may consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can help to detect and block malicious SQL code<\/a>, thereby preventing exploitation of this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
