Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Path Traversal in Deltek Maconomy. π **Consequences**: Attackers bypass security filters to access files outside the intended directory. Critical risk of data leakage.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-22 (Path Traversal). The system fails to sanitize special elements in resource/file paths. β οΈ **Flaw**: Improper input validation allows `../` sequences to escape restricted areas.
Q3Who is affected? (Versions/Components)
π’ **Affected**: Deltek Maconomy ERP Software. π¦ **Version**: Specifically **2.2.5**. π **Vendor**: Deltek (USA). Check if your instance matches this version.
Q4What can hackers do? (Privileges/Data)
π **Hackers Can**: Read sensitive system files (e.g., `/etc/passwd`). π **Access**: Restricted directories beyond the web root.β¦
π **Threshold**: Medium. The exploit targets the `PATH_INFO` in specific CGI endpoints. π **Config**: Requires access to the vulnerable web interface.β¦
π₯ **Public Exp**: YES. π **PoC**: Available on GitHub (ras313). π§ͺ **Proof**: `cgi-bin/Maconomy/MaconomyWS.macx1.W_MCS/etc/passwd` URI works. Nuclei templates also exist for scanning.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for the specific URI pattern: `/MaconomyWS.macx1.W_MCS/`. π‘ **Tool**: Use Nuclei or manual HTTP requests to test for `/etc/passwd` response.β¦
π§ **No Patch?**: Implement WAF rules to block `../` sequences in URL paths. π **Restrict**: Limit access to `/cgi-bin/` and specific `.macx1` endpoints.β¦
β‘ **Urgency**: HIGH. π¨ **Priority**: Critical. Public exploits exist. π **Published**: May 2019, but still active risk for unpatched systems. Patch NOW to prevent data exfiltration.
