CVE-2025-51683 is a blind SQL Injection vulnerability identified in mJobtime version 15.7.2. The flaw exists in the /Default.aspx/update_profile_Server endpoint, which processes POST requests without proper sanitization of input parameters. An unauthenticated attacker can craft malicious POST requests to inject arbitrary SQL statements, potentially compromising the backend database. Blind SQL Injection means the attacker cannot directly see query results but can infer data through response behavior or timing, enabling data extraction or manipulation over time. The vulnerability does not require any authentication or user interaction, increasing its risk profile. Although no public exploits or patches have been reported yet, the vulnerability's presence in a widely used workforce management application like mJobtime could lead to significant data breaches or service disruptions if exploited. The lack of a CVSS score indicates this is a newly published vulnerability, reserved since mid-2025 and disclosed in December 2025. The absence of patch links suggests that vendors or users must prioritize mitigation through secure coding practices and monitoring until official fixes are released.

For European organizations using mJobtime, this vulnerability poses a serious risk to confidentiality, integrity, and availability of sensitive workforce and operational data. Exploitation could lead to unauthorized access to employee records, payroll information, or other critical business data stored in the database. Data manipulation could disrupt business processes or corrupt records, while denial of service could impact operational continuity. Given the unauthenticated nature of the attack vector, any exposed mJobtime installation accessible over the network is vulnerable. This could affect sectors heavily reliant on workforce management software, including manufacturing, logistics, and services. The impact is amplified in regulated environments where data breaches can lead to significant compliance penalties under GDPR and other data protection laws.

Organizations should immediately audit their mJobtime deployments to identify vulnerable versions, particularly version 15.7.2. Until an official patch is released, implement web application firewall (WAF) rules to detect and block suspicious POST requests targeting the /Default.aspx/update_profile_Server endpoint. Employ input validation and parameterized queries in any custom integrations or extensions of mJobtime to prevent SQL injection. Monitor logs for unusual database query patterns or repeated failed requests indicative of blind SQLi attempts. Restrict network access to the application to trusted IPs where possible and enforce strict access controls. Engage with the vendor for timely patch updates and apply them promptly once available. Conduct regular security assessments and penetration testing focused on injection vulnerabilities to proactively identify and remediate risks.
