Lifecycle Timeline

Multiple stored cross-site scripting (XSS) vulnerabilities in the submit_add_user.asp endpoint of DDSN Interactive Acora CMS v10.7.1 allow attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the First Name and Last Name parameters.
AnalysisAI
Stored cross-site scripting (XSS) vulnerabilities in DDSN Interactive Acora CMS v10.7.1 allow unauthenticated attackers to inject malicious scripts via the submit_add_user.asp endpoint's First Name and Last Name parameters, enabling arbitrary JavaScript execution in the context of victim browsers. Public proof-of-concept code is available on GitHub; no patch information or CVSS/EPSS quantification is currently available.
Technical ContextAI
The vulnerability exists in the submit_add_user.asp endpoint of Acora CMS, a content management system component developed by DDSN Interactive. The affected parameters (First Name and Last Name) accept unsanitized user input that is stored in the application's database and subsequently rendered in HTML responses without proper output encoding or escaping. This classic stored XSS flaw (CWE category: Improper Neutralization of Input During Web Page Generation) means that when any user views pages containing the injected payload, the malicious script executes with the privileges of the authenticated session, potentially allowing session hijacking, credential theft, or further lateral movement within the CMS.
RemediationAI
Immediate mitigation: upgrade DDSN Interactive Acora CMS to a patched version released by the vendor following this disclosure. Until a patch is available, implement input validation and output encoding at the application layer-specifically, sanitize First Name and Last Name parameters to reject or encode special characters (< > " ' &) before storage, and ensure all user-supplied data is HTML-entity-encoded when rendered in responses. Restrict access to the submit_add_user.asp endpoint via network controls or authentication requirements if operationally feasible. Consult DDSN Interactive vendor advisories at http://ddsn.com and the official Acora documentation at http://acora.com for confirmed patched versions and additional mitigation guidance. Review application logs for evidence of exploitation.
