CVE-2025-26524 is a medium-severity vulnerability affecting the RupeeWeb trading platform. This vulnerability exists due to missing rate limiting on OTP requests in certain API endpoints. An authenticated remote attacker could exploit this vulnerability by sending multiple OTP requests through vulnerable API endpoints, leading to OTP bombing or flooding on the targeted system.
The CVSS score assigned to this vulnerability is 5.1, indicating a medium severity. The attack vector is categorized as network-based, and the complexity of exploitation is low. Importantly, the attacker requires high privileges to exploit this vulnerability.
Risk to organizations includes potential disruptions to service availability due to the flooding of OTP requests. As such, organizations should prioritize patching immediately.
Currently, there is no public exploit confirmed for this vulnerability, and it has not been included in any known exploitation catalog.
Organizations should address this vulnerability in their patch management cycles to ensure the security and availability of their systems.
Vulnerability Details
The vulnerability is classified under CWE-799, indicating an issue related to improper control of a resource through its lifetime. The publication date for CVE-2025-26524 was February 14, 2025, and it was last modified on April 15, 2026.
Technical Analysis
The root cause of this vulnerability is the lack of rate limiting on OTP requests, which allows authenticated users to overwhelm the system with excessive requests. This can lead to denial of service conditions for legitimate users. The attack vector is network-based, requiring no user interaction, thus making it easier for attackers to exploit.
The attack complexity is low, and high privileges are required for exploitation. The impact on confidentiality and integrity is minimal, but availability is significantly affected due to the potential for flooding the OTP service.
Risk & Impact Analysis
Organizations utilizing the RupeeWeb trading platform need to assess the real-world risks associated with this vulnerability. The potential for OTP flooding represents a significant threat to service availability, directly impacting user trust and operational capabilities.
Given the CVSS score of 5.1, organizations should schedule remediation as part of their priority patch cycle. The urgency is heightened by the nature of the vulnerability, which could be exploited with relative ease by an authenticated user.
Furthermore, there is a significant blast radius associated with this vulnerability, as it could affect multiple users and services relying on OTP authentication within the platform.
