Q1What is this vulnerability? (Essence + Consequences)
đ¨ **Essence**: A critical authentication bypass in the HTTP(S) management module. đ **Consequences**: Unauthenticated remote attackers can gain full administrative access to the device.âŚ
đĄď¸ **Root Cause**: **CWE-287** (Improper Authentication). The flaw lies in how the HTTP(S) management module handles identity verification. It fails to properly validate credentials before granting access.
Q3Who is affected? (Versions/Components)
đ **Affected**: **Belden Hirschmann HiEOS LRS11**. Specifically, all versions **prior to 01.1.00**. This is an industrial Ethernet switch OS platform used in critical infrastructure.
Q4What can hackers do? (Privileges/Data)
đ **Attacker Capabilities**: Full **Admin Privileges**. Attackers can read, modify, or delete configuration data. They can also potentially disrupt industrial operations by changing network settings remotely.
Q5Is exploitation threshold high? (Auth/Config)
⥠**Exploitation Threshold**: **LOW**. No authentication (PR:N) is required. No user interaction (UI:N) is needed. The attack vector is Network (AV:N). This makes it extremely easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
đ **Public Exploit**: **No**. The `pocs` field is empty. While third-party advisories exist, there is no confirmed public Proof-of-Concept (PoC) or widespread wild exploitation reported yet.
Q7How to self-check? (Features/Scanning)
đ **Self-Check**: Scan for open HTTP/HTTPS management ports on Belden Hirschmann devices. Verify the running firmware version against **01.1.00**. If the version is older, the device is vulnerable.
Q8Is it fixed officially? (Patch/Mitigation)
â **Official Fix**: **Yes**. The vendor has issued a security bulletin (BSECV-2024-02). The fix is available by upgrading the HiEOS LRS11 firmware to version **01.1.00 or later**.
Q9What if no patch? (Workaround)
đ§ **No Patch Workaround**: If you cannot patch immediately, **restrict network access** to the management interface. Use firewalls to allow only trusted IP addresses to access the HTTP/HTTPS ports.âŚ
đĽ **Urgency**: **CRITICAL**. CVSS Score is **9.1 (High)**. Due to the lack of authentication requirement and high impact on confidentiality, integrity, and availability, immediate patching is strongly recommended.
