CVE-2026-108807 in EmployeeRecruitmentSystem
Summary
by MITRE • 10/12/2026
A vulnerability was found in krupalshah EmployeeRecruitmentSystem up to 922ff6d208278282e7c8e36d70d9ae356adec9fe. This affects the function mysql_query of the file source/adminregister.php of the component Registration Handler. Performing a manipulation results in sql injection. The attack may be initiated remotely. The exploit has been made public and could be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.

Analysis
by VulDB Data Team • 10/12/2026
The EmployeeRecruitmentSystem developed by krupalshah contains a critical security flaw within its Registration Handler component, specifically located in the source/adminregister.php file. The vulnerability stems from an improper implementation of database interaction functions, where user-supplied input is passed directly to the mysql_query function without adequate sanitization or validation. This architectural oversight allows for SQL injection attacks, which are among the most dangerous web application vulnerabilities due to their potential to compromise entire databases. Because the product utilizes a rolling release model rather than fixed version numbers, identifying specific affected builds based on traditional versioning is not feasible; however, any instance running code up to commit 922ff6d208278282e7c8e36d70d9ae356adec9fe remains susceptible. The lack of response from the vendor upon notification indicates that this software is effectively abandoned and no longer receives security patches or support, leaving users exposed to known exploits indefinitely.
From a technical perspective, the core issue lies in the failure to escape special characters within SQL statements constructed via dynamic queries. When an attacker submits maliciously crafted input through registration forms or related administrative interfaces, they can manipulate the underlying SQL logic executed by the database server. This aligns with CWE-89, which defines Improper Neutralization of Special Elements used in an SQL Command. The absence of parameterized queries or prepared statements means that string concatenation is likely being used to build query strings, creating a direct pathway for injection. Since the mysql_query function was deprecated and later removed in newer PHP versions, this codebase also reflects outdated technology stacks that lack modern security features such as native support for bound parameters, further exacerbating the risk of exploitation.
The operational impact of this vulnerability is severe, particularly given its remote exploitability. An attacker can initiate attacks from a distant location without requiring prior authentication or physical access to the network infrastructure. Successful exploitation could lead to unauthorized data disclosure, allowing attackers to extract sensitive information such as employee personal details, login credentials, and internal system configurations stored in the recruitment database. Furthermore, depending on the privileges granted to the database user account running the application, an attacker might escalate their access to modify or delete records entirely, disrupting business operations and compromising data integrity. The fact that public exploits exist significantly lowers the barrier to entry for malicious actors, increasing the likelihood of automated scanning tools targeting this specific software variant across the internet.
This vulnerability maps directly to MITRE ATT&CK technique T1190, which covers Exploit Public-Facing Application. Attackers frequently leverage known vulnerabilities in widely deployed or easily accessible web applications to gain initial access to target environments. In the context of recruitment systems, the stolen data often serves as a valuable commodity for identity theft campaigns or can be used as stepping stones for further lateral movement within an organization if the compromised database shares credentials with other internal services. The rolling release model complicates remediation efforts because users cannot simply upgrade to a specific patched version; instead, they must manually review code changes or migrate away from this unsupported platform entirely.
Mitigation strategies are limited due to the abandoned status of the software. Immediate action should involve isolating any instances of this system behind strict network access controls if it must remain online temporarily. However, the most effective long-term solution is to decommission the EmployeeRecruitmentSystem and replace it with a supported alternative that adheres to secure coding standards such as OWASP Top 10 guidelines. For organizations currently running this software, implementing a Web Application Firewall can provide some level of protection by filtering out common SQL injection patterns in incoming traffic. Additionally, ensuring that database accounts operate under the principle of least privilege will limit the damage an attacker can inflict even if they succeed in exploiting the vulnerability. Regular security audits and code reviews are essential for any system handling sensitive personnel data to prevent similar oversights in future development cycles.
