Lifecycle Timeline
1DescriptionCVE.org
HCL DFXAnalytics is affected by a Buffer Overflow vulnerability that can lead to a Denial of Service (DoS). The application fails to properly validate input sizes, allowing an attacker to pass an excessive amount of information into a memory container, which can cause the system to crash or become unresponsive. To mitigate this flaw, comprehensive input length checks must be implemented and enforced on both the client and server sides.
AnalysisAI
Stack-based buffer overflow in HCL DFXAnalytics allows remote unauthenticated attackers to crash or render the application unresponsive by submitting excessively large input values that bypass missing server-side length validation. The vulnerability carries a CVSS 3.1 score of 5.3 (Medium) with availability as the sole impact dimension - no confidentiality or integrity exposure is present, and remote code execution has not been indicated. …

Vulnerability AssessmentAI
| Exploitation | No special configuration is required - the CVSS vector AV:N/AC:L/PR:N/UI:N/S:U indicates this is remotely exploitable against default configurations of HCL DFXAnalytics without authentication or user interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.3 (Medium) correctly reflects a bounded risk profile: the attack is low-complexity and requires no authentication (AV:N/AC:L/PR:N/UI:N), but scope is unchanged and impact is limited exclusively to availability at the Low tier (A:L), meaning partial or intermittent service disruption rather than a full outage or data breach. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated remote attacker identifies a DFXAnalytics data-submission or API endpoint exposed over the network, then sends a crafted request containing an input field that exceeds the server's fixed-size stack buffer. The buffer overflow corrupts adjacent stack memory, causing the process to crash and rendering the analytics service unavailable until it is manually or automatically restarted. |
| Remediation | Consult the HCL vendor advisory at https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0131787 for patch availability; no exact fixed version number was included in the available input data, so a patched release version cannot be independently confirmed at this time. … Detailed patch versions, workarounds, and compensating controls in full report. |
