01

What, why and how

A vulnerability in a known login mechanism allows unauthenticated attackers to execute API calls without requiring user credentials. RBAC helps limit the exposure but does not eliminate risk.

What

A vulnerability in a known login mechanism allows unauthenticated attackers to execute API calls without requiring user credentials. RBAC helps limit the exposure but does not eliminate risk.

Why

The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound communication to external components.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path
a network path → Use of Hard-coded Password → cause the confidentiality, integrity or availability impact described by the vendor

CWE-259: Use of Hard-coded Password. The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound communication to external components.

BSI · German · WID-SEC-W-2025-1867Commvault Backup & Recovery: Mehrere Schwachstellen

Ein entfernter anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Commvault Backup & Recovery ausnutzen, um sich erweiterte Berechtigungen zu verschaffen, beliebigen Code auszuführen und Sicherheitsmaßnahmen zu umgehen.

Official advisory
NCSC-NL · Dutch · NCSC-2025-0265Kwetsbaarheden verholpen in Commvault

De kwetsbaarheden bevinden zich in versies van Commvault vóór 11.36.60. De eerste kwetsbaarheid stelt niet-geauthenticeerde aanvallers in staat om API-aanroepen uit te voeren via een bekend inlogmechanisme, wat kan leiden tot ongeautoriseerde toegang tot gevoelige gegevens of functionaliteiten binnen de Commvault-omgeving. De tweede kwetsbaarheid betreft een pad-traversal probleem dat door externe aanvallers kan worden misbruikt, wat kan leiden tot ongeautoriseerde toegang tot het bestandssysteem en mogelijk tot remote code execution. De derde kwetsbaarheid is het gevolg van onvoldoende invoervalidatie, waardoor aanvallers commandoregelargumenten kunnen manipuleren, wat hen mogelijk toegang kan geven tot een geldige gebruikerssessie met lage privileges. Deze kwetsbaarheden verhogen het risico op datacompromittatie en schendingen van de systeemintegriteit.

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Fix not verified
Affected
11.32.0 ≤ 11.32.101; 11.36.0 ≤ 11.36.59
Fixed
No fixed version is explicitly recorded in the structured CVE data.
Action
No verified patch reference is present in the current structured sources. Check the vendor advisory before making a change.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
