Patch available

What, why and how

A CWE-306: Missing Authentication for Critical Function The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. Affected Products: APC Easy UPS Online Monitoring Software (Windows 7, 10, 11 & Windows Server 2016, 2019, 2022 - Versions prior to V2.5-GA), APC Easy UPS Online Monitoring Software (Windows 11, Windows Server 2019, 2022 - Versions prior to V2.5-GA-01-22261), Schneider Electric Easy UPS Online Monitoring Software (Windows 7, 10, 11 & Windows Server 2016, 2019, 2022 - Versions prior to V2.5-GS), Schneider Electric Easy UPS Online Monitoring Software (Windows 11, Windows Server 2019, 2022 - Versions prior to V2.5-GS-01-22261)

What

Why

A security-sensitive function is reachable without the authentication check that should protect it.

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.

What

Why

A security-sensitive function is reachable without the authentication check that should protect it.

How

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.

None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path: a network path → Missing Authentication for Critical Function → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface: Network
Privileges required: None: unauthenticated exploitation is possible
User interaction: None
Attack complexity: Low: no specialised conditions are recorded
Security boundary: Unchanged: impact remains within the vulnerable component's security authority
Weakness ? CWE means Common Weakness Enumeration: a standard category for the underlying weakness.: CWE-306 ↗
CWE-306: Missing Authentication for Critical Function. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
