CVE-2025-52608: HCL iControl Cookie Security Vulnerability

CVE-2025-52608 Overview

CVE-2025-52608 affects HCL iControl through a missing cookie attributes weakness tracked under [CWE-614]. The application fails to set the Secure and SameSite attributes on session cookies. The cookie Path attribute is also set to root (/), broadening cookie exposure across the application namespace. An attacker on the network path can attempt to intercept cookies transmitted over unencrypted channels or leverage cross-site request scenarios to misuse session state. Exploitation requires specific conditions, including some level of privilege and active user sessions, which reduces practical impact. The issue is categorized as a configuration and design flaw rather than a memory safety or code execution defect.

Critical Impact
Cookies without Secure and SameSite attributes may be exposed over cleartext channels or sent during cross-site requests, enabling session-related abuse against authenticated HCL iControl users.

Affected Products

HCL iControl (vendor advisory does not enumerate specific affected versions in public NVD data)

Technical Details for CVE-2025-52608

Vulnerability Analysis

The vulnerability stems from improper cookie attribute configuration in HCL iControl. Cookies issued by the application omit the Secure flag, allowing browsers to transmit them over plaintext HTTP if any non-TLS endpoint exists. The cookies also omit the SameSite attribute, which defaults to lax behavior in modern browsers but may permit cookie transmission during cross-site contexts in older clients. Additionally, the cookie Path is set to /, meaning the cookie applies to every endpoint under the application root. Combined, these attributes weaken the isolation properties that browsers rely on to protect session state. The issue maps to [CWE-614] (Sensitive Cookie in HTTPS Session Without Secure Attribute).

Root Cause

The root cause is the application's failure to explicitly assign protective cookie attributes when issuing Set-Cookie response headers. Developers did not specify Secure, SameSite, or a restrictive Path value during cookie creation. Without these attributes, browsers apply permissive defaults that do not prevent transmission over insecure channels or cross-site requests.

Attack Vector

The attack vector is network based. An adversary positioned to observe network traffic or able to induce a victim to navigate cross-site can attempt to capture or trigger transmission of the affected cookies. Successful abuse requires an authenticated victim session and additional conditions, such as the presence of a non-HTTPS endpoint or a vulnerable cross-site request flow. Exploitation does not yield code execution or data modification beyond limited integrity impact on session-bound operations. No public proof-of-concept exploit, exploit database entry, or CISA KEV listing is associated with this CVE.

No verified exploitation code is available. Refer to the HCL Software Knowledge Article for vendor-provided technical details.

Detection Methods for CVE-2025-52608

Indicators of Compromise

HTTP responses from HCL iControl containing Set-Cookie headers without Secure or SameSite attributes
Cookie values transmitted over HTTP (port 80) traffic to or from iControl endpoints
Unexpected session reuse from network locations differing from the original authentication source

Detection Strategies

Inspect HTTP response headers from iControl endpoints and flag Set-Cookie values missing Secure, SameSite, or with Path=/
Correlate authenticated session activity with TLS termination logs to identify cookies transmitted over plaintext
Review web proxy and reverse proxy logs for cross-origin requests carrying iControl session cookies

Monitoring Recommendations

Enable continuous monitoring of HTTP response headers for the iControl application across all ingress points
Alert on cleartext HTTP traffic destined for iControl hostnames or virtual hosts
Track session anomalies such as concurrent use of the same cookie from disparate source addresses or user agents

How to Mitigate CVE-2025-52608

Immediate Actions Required

Apply vendor guidance from the HCL Software Knowledge Article for CVE-2025-52608
Enforce HTTPS-only access to HCL iControl by disabling or redirecting any HTTP listeners
Rotate active session cookies after applying the fix to invalidate any previously exposed sessions

Patch Information

HCL has published remediation guidance in knowledge article KB0131061. Administrators should consult the vendor advisory for the patched build numbers and configuration changes specific to their iControl deployment. No third-party patch is available.

Workarounds

Configure an upstream reverse proxy or web application firewall to rewrite Set-Cookie headers and inject Secure, SameSite=Strict or SameSite=Lax, and a scoped Path value
Enforce HTTP Strict Transport Security (HSTS) on the iControl hostname to prevent browsers from sending cookies over plaintext
Restrict iControl access to trusted network segments until the vendor remediation is applied

bash

# Example reverse proxy header rewrite (nginx)
proxy_cookie_flags ~ secure samesite=strict;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
