A SQL Injection vulnerability on an endpoint in BEIMS Contractor Web, a legacy product that is no longer maintained or patched by the vendor, allows an unauthorised user to retrieve sensitive database contents via unsanitized parameter input. This vulnerability occurs due to improper input validation on /BEIMSWeb/contractor.asp endpoint and successful exploitation requires a contractor.asp endpoint open to the internet. This vulnerability allows attackers to execute arbitrary SQL commands, compromising the confidentiality, integrity and potentially the availability of the database.

Version 5.7.139

has been confirmed as vulnerable. Other versions have not been confirmed by the vendor and users should assume that all versions of BEIMS Contractor Web may be impacted until further guidance is provided by the vendor.

ZUUSE BEIMS ContractorWeb .NET 5.18.0.0 is vulnerable to Cross-Site Request Forgery (CSRF) on /CWEBNET/ authenticated pages. A successful CSRF attack can force the user to modify state: creating users, changing an email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application.

ZUUSE BEIMS ContractorWeb .NET 5.18.0.0 allows access to various /UserManagement/ privileged modules without authenticating the user; an attacker can misuse these functionalities to perform unauthorized actions, as demonstrated by Edit User Details.
