The vulnerability identified as CVE-2017-7428 affects NetIQ iManager versions 3.x prior to 3.0.3.1, specifically targeting the secure communication protocols between the application and Apache Tomcat web server. This issue stems from improper handling of TLS connection renegotiation processes which creates potential security weaknesses in the authentication and data transmission mechanisms. The flaw exists within the cryptographic protocol implementation where the system fails to properly validate or manage the renegotiation of secure connection parameters during active sessions.
The technical implementation of this vulnerability lies in the inadequate validation of TLS renegotiation requests within the NetIQ iManager application layer. When establishing communication with Tomcat servers, the application does not sufficiently verify the authenticity of renegotiation attempts, potentially allowing malicious actors to exploit this weakness during active sessions. This creates opportunities for man-in-the-middle attacks where attackers can manipulate connection parameters and potentially intercept or modify sensitive data transmissions. The vulnerability specifically impacts the cryptographic handshake process and connection parameter validation mechanisms.
The operational impact of CVE-2017-7428 extends beyond simple data interception, potentially enabling attackers to escalate privileges and gain unauthorized access to administrative functions within the NetIQ iManager environment. Organizations using affected versions may experience compromised authentication processes where session tokens and credentials could be manipulated or stolen during active connections. The vulnerability affects the integrity and confidentiality of data exchanged between the iManager application and backend Tomcat services, potentially exposing sensitive enterprise information including user credentials, configuration data, and administrative access details. This weakness particularly impacts organizations relying on NetIQ's identity and access management solutions.
Mitigation strategies for CVE-2017-7428 should prioritize immediate patching to version 3.0.3.1 or later, which addresses the TLS renegotiation validation issues. Organizations should also implement network-level monitoring to detect unusual connection parameter changes and establish strict TLS configuration policies that disable insecure renegotiation features. The mitigation approach aligns with CWE-327 standards regarding weak cryptographic algorithms and improper implementation of security protocols, while also addressing ATT&CK techniques related to credential access and privilege escalation through network protocol manipulation. Security teams should conduct comprehensive vulnerability assessments to identify any remaining instances of the vulnerable software and implement additional network segmentation measures to limit potential attack surface exposure.
