CVE-2026-35141 in DFXAnalytics
Summary
by MITRE • 07/16/2026
HCL DFXAnalytics is affected by a Login Replay Attack vulnerability. The application allows a remote attacker to intercept, delay, or fraudulently retransmit valid authentication data to achieve unauthorized access. To mitigate this risk, the application must implement a mechanism to include timestamps with every message, ensuring that messages exceeding a specific age threshold are automatically rejected by the recipient system.

The HCL DFXAnalytics login replay attack vulnerability represents a critical security flaw that undermines the integrity of the authentication process through unauthorized access exploitation. This weakness allows remote attackers to intercept legitimate authentication tokens or credentials and subsequently retransmit them at a later time to gain unauthorized system access. The vulnerability stems from insufficient validation mechanisms within the authentication flow, creating an opening for attackers to manipulate the timing and sequence of authentication messages. Such attacks exploit the fundamental principle that valid authentication data should not be reusable beyond its intended session context, making this a significant concern for any enterprise-level analytics platform handling sensitive business data.
The technical implementation of this vulnerability manifests through the absence of proper time-based validation mechanisms within the authentication protocol. When authentication tokens or credentials are transmitted, they lack embedded timestamps or expiration indicators that would normally prevent reuse of previously valid authentication data. Attackers can capture these authentications during transmission and replay them at their convenience to bypass authentication controls entirely. The flaw operates at the protocol level where session management does not enforce temporal constraints on authentication validity, creating a window of opportunity for attackers to exploit the system's trust in previously validated credentials. This vulnerability directly relates to CWE-346 known as "Improper Verification of Cryptographic Signature" and more specifically addresses CWE-306 "Missing Authentication for Critical Function" when considering the broader authentication framework failure.
The operational impact of this login replay attack vulnerability extends beyond simple unauthorized access, potentially leading to complete system compromise and data breaches. An attacker exploiting this flaw could gain persistent access to sensitive analytics data, manipulate business intelligence systems, or use compromised credentials to escalate privileges within the network. The delayed nature of the attack means that traditional intrusion detection systems might not immediately identify the unauthorized access pattern, as the authentication tokens themselves are valid when first captured. This vulnerability affects the confidentiality, integrity, and availability of the DFXAnalytics platform, potentially exposing business-critical information and disrupting legitimate operations. Organizations relying on this analytics solution face increased risk of competitive intelligence theft, regulatory non-compliance, and financial loss due to unauthorized system access.
Effective mitigation strategies must focus on implementing robust time-based validation mechanisms that incorporate timestamps within every authentication message exchanged between client and server components. The system should enforce strict temporal boundaries where messages exceeding predefined age thresholds are automatically rejected by the recipient system, typically implemented through nonce validation or timestamp comparison algorithms. Additional protective measures include implementing session timeout mechanisms, requiring multi-factor authentication for critical functions, and establishing continuous monitoring of authentication patterns for anomalous replay activity. These controls align with ATT&CK technique T1566.002 "Phishing: Spearphishing Attachment" and T1562.008 "Impair Defenses: Modify Authentication Process" while addressing the core weakness identified in the vulnerability description. Organizations should also consider implementing cryptographic token binding, challenge-response mechanisms, and regular security assessments to ensure that authentication protocols remain resilient against replay attacks and maintain compliance with industry standards such as NIST SP 800-63 for digital identity management.
