This vulnerability resides within the Rotem Dynamics Rotem CRM system, specifically in the OTP URI Interface component accessible through the path /LandingPages/api/otp/send. The flaw manifests when processing requests containing an ID parameter and method parameter set to sms, creating a information exposure condition through discrepancy. The vulnerability classification as problematic indicates a significant security risk that could compromise sensitive data. The issue affects versions up to 20230729, suggesting this represents a known weakness that has persisted for some time without vendor resolution. The fact that no response was received from the vendor upon early disclosure indicates potential vendor negligence or lack of prioritization for this security concern. The vulnerability operates through a discrepancy in information exposure, meaning that when the system processes the OTP sending request, it inadvertently reveals information that should remain protected. This exposure occurs through the API endpoint that handles one-time password delivery mechanisms, which are critical for authentication security. The vulnerability's remote exploitation capability means attackers can initiate the attack without requiring physical access to the system, making it particularly dangerous in networked environments.
The technical implementation of this vulnerability involves improper handling of the ID parameter within the OTP sending API endpoint. When a request is made to the /LandingPages/api/otp/send?id=[ID]&method=sms path, the system fails to properly validate or sanitize the ID parameter before processing the SMS delivery request. This creates a scenario where information disclosure occurs through the discrepancy in how the system handles the parameter, potentially exposing sensitive identifiers or authentication details. The vulnerability falls under CWE-200, which addresses information exposure, and more specifically relates to CWE-352, which covers cross-site request forgery issues. The discrepancy in information exposure suggests that the system may be revealing internal state information, user identifiers, or session details through the response mechanism. This type of vulnerability represents a fundamental flaw in the system's access control and information flow management, where the OTP system's interface does not properly enforce security boundaries. The attack vector through the URI interface indicates that this vulnerability can be exploited via standard web requests, making it accessible to any attacker with network access to the system.
The operational impact of this vulnerability extends beyond simple information disclosure, as it could enable attackers to gain unauthorized access to user accounts or sensitive business data within the Rotem CRM system. The exposure of OTP-related information could allow adversaries to predict or bypass authentication mechanisms, potentially leading to full system compromise. The vulnerability's remote exploitability means that attackers can target the system from anywhere on the internet, without requiring local network access or physical presence. This creates a significant risk for organizations using the Rotem CRM system, as it exposes their customer relationship management data to potential unauthorized access. The information exposure through discrepancy could reveal user identifiers, account details, or system internals that would otherwise remain protected. The lack of vendor response adds additional risk as organizations may not receive timely patches or updates to address the vulnerability, leaving systems exposed for extended periods. This vulnerability could also facilitate further attacks by providing attackers with information needed to conduct more sophisticated exploitation techniques.
Organizations utilizing Rotem CRM systems should immediately implement mitigations to address this vulnerability while awaiting potential vendor patches or updates. The primary mitigation strategy involves implementing proper input validation and sanitization for the ID parameter within the OTP sending endpoint, ensuring that all parameters are properly validated before processing. Network segmentation and access controls should be strengthened to limit access to the vulnerable API endpoints, particularly restricting access to authenticated users only. Implementing rate limiting and monitoring for unusual patterns in OTP sending requests can help detect potential exploitation attempts. Organizations should also consider disabling the vulnerable endpoint if it is not critical for business operations, or implementing additional authentication mechanisms for OTP delivery requests. The mitigation approach should follow established security frameworks such as those outlined in the NIST Cybersecurity Framework and align with MITRE ATT&CK framework techniques related to credential access and information gathering. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other system components. Organizations should also consider implementing web application firewalls to help detect and block malicious requests targeting the vulnerable API endpoint. The lack of vendor response underscores the importance of maintaining internal security measures and having contingency plans for unsupported software vulnerabilities.
