Cross-site request forgery (CSRF) vulnerability in esop/toolkit/profile/regData.do in Bravo Tejari Procurement Portal allows remote authenticated users to hijack the authentication of application users for requests that modify their personal data by leveraging lack of anti-CSRF tokens.

In Bravo Tejari Procurement Portal, uploaded files are not properly validated by the application either on the client or the server side. An attacker can take advantage of this vulnerability and upload malicious executable files to compromise the application, as demonstrated by an esop/evm/OPPreliminaryForms.do?formId=857 request.
