The discovered vulnerability in Dahan Software pertains to unauthorized admin access. This vulnerability could allow unauthorized users to potentially bypass security controls and access sensitive backend administrative functions. Such vulnerabilities, if exploited, can lead to severe security risks including data breaches or unauthorized changes to system configurations. The backend functions hold critical control over the software's operations, making access control essential for security integrity. The bypass vulnerability emerges due to insufficient validation at the VerifyCodeServlet endpoint, leading to potential unauthorized privilege escalation. The lack of strict input validation and security checks makes applications susceptible to this bypass.

Technical details of the vulnerability center around inadequate access controls at specific URL endpoints related to system configuration and administration. URLs such as ‘/vipchat/setup/opr_licenceinfo.jsp’ and equivalents grant access based on improperly verified credentials. Attackers can leverage these endpoints to retrieve configuration files and license details using crafted HTTP GET requests. The vulnerability is rooted in the failure to enforce proper authentication mechanisms, especially in management interfaces exposed to insecure networks. Attackers with network access to these endpoints can exploit them to infiltrate deep into administrative setups without legitimate credentials.

If exploited, this vulnerability can grant attackers unauthorized access to administrative functionalities of Dahan Software. This could potentially allow them to alter configurations, steal sensitive data, or disrupt services by executing unauthorized actions. Such activities may lead to unauthorized data exposure, manipulation of critical systems, and erosion of trust in the affected institution. The attack could be used as a staging ground for further exploitation, compromising the integrity of digital government services. These actions can significantly harm the institution’s operational capabilities and reputation.
