CVE-2026-35110 in AION
Summary
by MITRE • 11/06/2026
HCL AION is affected by a vulnerability where encrypted (HTTPS) communication was not enforced for all requests. Data may be transmitted over unencrypted connections and intercepted by an attacker on the network, potentially resulting in unintended behavior or security impact under certain conditions.

The identified vulnerability within HCL AION represents a critical failure in enforcing transport layer security protocols across the entire application surface. Specifically, the system fails to mandate encrypted communication via HTTPS for all incoming and outgoing requests. This architectural oversight allows sensitive data to be transmitted over unencrypted HTTP connections under certain conditions or for specific endpoints that were not explicitly configured with strict security policies. In a modern enterprise environment where applications are frequently accessed from various networks including public Wi-Fi, corporate intranets, or compromised local area networks, the absence of mandatory encryption creates a significant attack vector. The core technical flaw lies in the application's configuration logic which permits fallback to plaintext communication rather than rejecting non-encrypted requests outright. This behavior violates fundamental security principles regarding data integrity and confidentiality during transit.
From an operational perspective, this vulnerability exposes users and administrators to several severe risks. An attacker positioned on the same network segment as the HCL AION server can perform a man-in-the-middle attack to intercept sensitive information such as authentication credentials, session tokens, or proprietary business logic contained within API responses. Because the communication is not encrypted, the data remains in cleartext, making it trivial for an adversary with basic networking tools like Wireshark or tcpdump to capture and read this information without needing cryptographic keys. Furthermore, if the application does not strictly enforce HTTPS redirection at the web server level but relies on application-level checks that can be bypassed, attackers might also attempt session hijacking by stealing active cookies transmitted over these unencrypted channels. This could lead to unauthorized access to administrative functions or manipulation of user sessions resulting in unintended system behavior and potential data breaches.
This vulnerability aligns with CWE-319 which classifies the use of a cleartext protocol that transmits sensitive information without cryptographic protection. It also relates closely to CWE-648 regarding the misuse of trusted domain names if the application incorrectly trusts unencrypted connections from specific sources, although the primary issue is the lack of encryption enforcement itself. In terms of offensive security frameworks such as MITRE ATT&CK this flaw facilitates techniques associated with Network Sniffing and Credential Access allowing adversaries to passively gather sensitive data or actively manipulate traffic flows. The impact extends beyond simple eavesdropping; if integrity checks are also compromised due to the lack of encryption, attackers could modify requests in transit leading to injection attacks or logic flaws that exploit the trust placed in unverified network payloads.
To mitigate this vulnerability organizations must implement a multi-layered defense strategy starting with strict configuration management at both the application and infrastructure levels. The primary remediation involves configuring the web server or reverse proxy hosting HCL AION to enforce HTTPS for all requests by redirecting any HTTP traffic to its HTTPS equivalent using status code 301 or 302 redirects. Additionally enabling Strict-Transport-Security headers ensures that browsers and clients remember to always use secure connections for a specified period preventing downgrade attacks. It is crucial to audit the application configuration files to identify specific endpoints or modules where encryption might be disabled by default or through misconfiguration ensuring they are updated to require TLS 1.2 or higher with strong cipher suites. Regular vulnerability scanning should include checks for mixed content issues and unencrypted API calls to ensure no part of the communication channel remains vulnerable to interception.
