Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: N-able N-Central UI Auth Bypass. π **Consequences**: Attackers gain unauthorized access to restricted areas without credentials. Total loss of confidentiality and integrity for the UI.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-288 (Authentication Bypass). The flaw lies in the User Interface authentication mechanism, allowing bypass without proper verification.
Q3Who is affected? (Versions/Components)
π’ **Affected**: N-able N-Central. π **Versions**: All versions **prior to 2024.2**. If you are running an older build, you are at risk.
Q4What can hackers do? (Privileges/Data)
π» **Capabilities**: Hackers can access **restricted areas** of the UI. π **Impact**: High Confidentiality (C:H) and High Integrity (I:H) impact. No direct Availability (A:N) impact noted.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: LOW. π« **Auth**: No authentication required. π±οΈ **UI**: No user interaction needed. π **Vector**: Network (AV:N). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit**: Yes. Public PoC available via ProjectDiscovery Nuclei templates. π **Wild Exploitation**: Likely, given the low barrier to entry and public template.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for N-able N-Central versions < 2024.2. Use Nuclei templates for CVE-2024-28200. Check for unauthenticated access to admin endpoints.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes. Upgrade to **N-able N-Central 2024.2** or later. Official advisory released by N-able on July 1, 2024.
Q9What if no patch? (Workaround)
π§ **Workaround**: If patching is delayed, restrict network access to the N-Central UI. Implement WAF rules to block unauthenticated requests to sensitive endpoints.
