Deeper analysis
CVE-2023-45542 is a reflected cross-site scripting vulnerability in mooSocial version 3.1.8. The flaw exists in the Search function, where the q parameter does not adequately sanitize user-supplied input, allowing an attacker to inject and execute arbitrary script code in the context of a victim's browser.
An unauthenticated remote attacker can exploit the issue by crafting a malicious URL containing a script payload in the q parameter and tricking a user into clicking it. Successful exploitation enables theft of sensitive information such as session cookies or other client-side data, with impacts limited to confidentiality and integrity under the reported CVSS vector.
