AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N
MitM downgrade requires network positioning (AC:H) and victim browsing action (UI:R), but no attacker privileges; confidentiality rated L because cleartext interception exposes session data.
Primary rating from Vendor (HCL).

Lifecycle Timeline
1DescriptionCVE.org
HCL DFXAnalytics is affected by a Missing HTTP Strict-Transport-Security Header vulnerability. The application fails to implement the HTTP Strict Transport Security (HSTS) policy within its responses, which could allow a remote attacker to downgrade the communication channel to an unencrypted connection (HTTP) and conduct man-in-the-middle (MitM) attacks. To remediate this, the application must include the "Strict-Transport-Security" header in all web application responses.
AnalysisAI
Missing HSTS header in HCL DFXAnalytics exposes authenticated sessions to protocol downgrade and man-in-the-middle attacks by network-positioned adversaries. All versions per the CPE wildcard are affected, and the application fails to include the Strict-Transport-Security response header, leaving browsers without enforcement of HTTPS-only communication. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to achieve a network-on-path position between the victim's browser and the HCL DFXAnalytics server - for example via ARP spoofing, rogue Wi-Fi access point, or BGP hijacking - which is the source of the AC:H rating. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.1 (Low) reflects the realistic difficulty of exploitation: AV:N confirms the attack surface is network-facing, but AC:H (high attack complexity) acknowledges that a network-adjacent or on-path position is required to conduct the downgrade, and PR:L indicates the vendor considers an authenticated context necessary. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a network-adjacent position - such as on a shared corporate Wi-Fi segment or via ARP cache poisoning - intercepts a victim user's initial HTTP request to HCL DFXAnalytics before the browser can enforce HTTPS. The attacker uses an SSL-stripping tool to maintain a TLS connection upstream to the server while serving cleartext HTTP downstream to the victim, transparently proxying and reading or modifying application traffic including session cookies or submitted data. … |
| Remediation | The primary remediation is to configure all HCL DFXAnalytics web application response handlers to emit the Strict-Transport-Security header, for example: Strict-Transport-Security: max-age=31536000; includeSubDomains. … Detailed patch versions, workarounds, and compensating controls in full report. |
