The vendor explicitly identifies these products as affected by this CVE.

  • APOGEE PXC Series (BACnet)
  • APOGEE PXC Series (P2 Ethernet)
  • TALON TC Series (BACnet)
Summary
Affected devices contain a weak encryption mechanism based on a hard-coded key. This could allow an attacker to guess or decrypt the password from the cyphertext.
Remediation
Use strong, hard to guess passwords

01

What, why and how

A vulnerability has been identified in APOGEE PXC Series (BACnet) (All versions), APOGEE PXC Series (P2 Ethernet) (All versions), TALON TC Series (BACnet) (All versions). Affected devices contain a weak encryption mechanism based on a hard-coded key. This could allow an attacker to guess or decrypt the password from the cyphertext.

What

A vulnerability has been identified in APOGEE PXC Series (BACnet) (All versions), APOGEE PXC Series (P2 Ethernet) (All versions), TALON TC Series (BACnet) (All versions). Affected devices contain a weak encryption mechanism based on a hard-coded key. This could allow an attacker to guess or decrypt the password from the cyphertext.

Why

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

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.
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 → Inadequate Encryption Strength → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction

Low: no specialised conditions are recorded

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-326 ↗

CWE-326: Inadequate Encryption Strength. The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
