CVE-2023-44393 Scanner

Piwigo is a widely used photo gallery application used by photographers, organizations, and individuals for managing and publishing photo collections. It is equipped with various features, including photo organization, theme customization, and plugin support. Piwigo facilitates collaboration and photo sharing, making it suitable for community and personal use. The software is compatible with a wide variety of hosting environments, easing deployment and maintenance. Its open-source nature encourages community involvement and constant updates. Organizations rely on Piwigo's modular architecture to expand features through plugins.

The Cross-Site Scripting (XSS) vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. This flaw typically affects the admin panel within Piwigo, especially where there is insufficient input validation. Attackers leverage this vulnerability to execute scripts in the context of the user's browser. It poses significant risks to user confidentiality and data integrity. The vulnerability ranks medium in severity but can cause notable issues when exploited. Scripting attacks can vary based on the scripts used and their intended impact.

The technical details of the vulnerability involve the improper sanitization of the `plugin_id` parameter within the admin panel. When an administrator accesses a specially crafted URL, the user's browser executes injected scripts. This XSS vulnerability does not require prior authentication, increasing its potential impact. The injected scripts execute with the same permissions as the user accessing the page. Given its involvement with admin pages, the vulnerability could lead to higher consequences. The solution involves thoroughly updating the input validation processes to sanitize parameters like `plugin_id` adequately.

Once exploited, the XSS vulnerability can result in several adverse effects. Attackers might hijack administrator sessions, leading to further unauthorized access. They could manipulate content on the website, impacting user trust and site integrity. Sensitive data theft could occur if the script captures authentication credentials or other private information. Execution of arbitrary commands within the user's session context is possible. The theft of content from local storage or cookies is another potential outcome. The remediation steps are critical to prevent long-term impacts on system security and integrity.
