CVE-2023-5021 is a problematic cross-site scripting (XSS) vulnerability identified in SourceCodester AC Repair and Services System versions 1.0 through 1.0. This vulnerability allows attackers to inject malicious scripts into the system, potentially compromising user accounts and data. A patch, version 1.0.1, has been released to address this issue.
The XSS vulnerability in AC Repair and Services System allows an attacker to inject arbitrary JavaScript code into the application. This code can then be executed in the context of a user's browser when they visit a vulnerable page. An attacker could leverage this to steal session cookies, redirect users to malicious websites, or deface the application. The impact is amplified if the application is used to manage sensitive customer data, as an attacker could potentially gain access to this information. While the CVSS score is LOW, the ease of exploitation and potential for user compromise warrants immediate attention.
CVE-2023-5021 was disclosed on September 17, 2023. There are currently no publicly available proof-of-concept exploits. The vulnerability is not listed on the CISA KEV catalog at the time of this writing. Given the relatively simple nature of XSS vulnerabilities, it is possible that this vulnerability will be actively exploited in the future.

The primary mitigation for CVE-2023-5021 is to immediately upgrade to version 1.0.1 of the AC Repair and Services System. If upgrading is not immediately feasible, consider implementing input validation and output encoding on the admin/?page=systeminfo/contactinformation page to sanitize user-supplied data. Web application firewalls (WAFs) can also be configured to detect and block XSS attempts targeting this specific endpoint. Regularly review and update security configurations to minimize the attack surface.
Update to a patched version or apply a solution that correctly filters or escapes user inputs in the affected function (admin/?page=system_info/contact_information) to prevent XSS code injection. Validate and sanitize input data before displaying it on the page.
