CVE-2026-121147 in iRA
Summary
by MITRE • 11/04/2026
This vulnerability exists in the iRA 2.0 and iRA.ev mobile applications due to improper implementation of SSL certificate pinning in the network security configuration, resulting in ineffective certificate pinning controls. An attacker positioned to intercept network traffic could exploit this vulnerability to intercept or modify communications between the application and its backend services.

The identified vulnerability stems from a critical misconfiguration within the iRA 2.0 and iRA.ev mobile applications, specifically concerning the implementation of SSL certificate pinning in their respective network security configurations. Certificate pinning is a security mechanism designed to prevent man-in-the-middle attacks by ensuring that an application only communicates with servers presenting certificates bound to specific public keys or hashes. In this instance, despite the apparent intent to enforce such controls through the network security configuration file, the implementation was flawed, rendering the pinning ineffective. This failure means that the applications do not strictly validate the identity of the server against a pre-defined set of trusted certificates, thereby leaving the communication channel vulnerable to interception and manipulation by malicious actors who can position themselves between the client application and the backend services.
From an operational perspective, this flaw significantly undermines the confidentiality and integrity of data transmitted between the mobile device and the remote servers. An attacker with network access, such as one operating on a compromised public Wi-Fi hotspot or performing a sophisticated man-in-the-middle attack within a private network, can intercept sensitive user information without detection. Because the application does not verify that the server's certificate matches the expected pinned value, it will accept any valid SSL/TLS certificate presented by an attacker using tools like Burp Suite or OWASP ZAP to proxy traffic. This allows for the extraction of personally identifiable information, authentication credentials, and financial data, as well as the potential injection of malicious payloads into the application's response stream, which could lead further exploitation on the client side.
This vulnerability aligns with CWE-295, Improper Certificate Validation, where software does not validate or incorrectly validates a certificate against its expected value. Furthermore, it relates to ATT&CK technique T1078, Valid Accounts, and potentially T1043, Commonly Used Port, as the attacker leverages standard network protocols to intercept traffic that should be strictly authenticated. The lack of effective pinning also touches upon CWE-926, Improper Export of Android Application Components, if the security configuration is not properly scoped or restricted within the application manifest, although the core issue remains the cryptographic validation failure during TLS handshakes.
To mitigate this risk, developers must implement robust certificate pinning directly within the application code rather than relying solely on network security configurations which can be more easily bypassed or misconfigured. This involves hardcoding the SHA-256 fingerprints of trusted certificates and validating them programmatically before establishing a connection. Additionally, implementing Certificate Transparency logs monitoring and using modern cryptographic libraries that support automatic pinning updates via mechanisms like Public Key Pinning with backup keys can enhance resilience against certificate authority compromises. Regular security audits and penetration testing focused on mobile application traffic analysis are essential to ensure that such configurations remain effective and resistant to common interception techniques.
