Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: EPyT-Flow suffers from **Insecure Deserialization** via its REST API.β¦
π’ **Vendor**: WaterFutures (ERC Synergy Grant Water Futures). π¦ **Product**: EPyT-Flow (Python package for water network scenarios). β οΈ **Affected**: Versions **prior to 0.16.1**.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full **OS Command Execution** (RCE). π **Data**: High impact on Confidentiality, Integrity, and Availability (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. π **Network**: Attack Vector is Network (AV:N). π **Auth**: No Privileges Required (PR:N). π±οΈ **UI**: No User Interaction Required (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: No specific PoC code provided in the data. π **Status**: Advisory published (GHSA-74vm-8frp-7w68), but wild exploitation risk is high due to low complexity.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for EPyT-Flow versions < 0.16.1. π‘ **Monitor**: Look for abnormal REST API calls with complex JSON payloads targeting type fields. π **Code**: Check for custom deserializers in the API layer.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes! Upgrade to **EPyT-Flow v0.16.1** or later. π **Patch**: See GitHub release notes and commit 3fff9151494c7dbc72073830b734f0a7e550e385.
Q9What if no patch? (Workaround)
π§ **Workaround**: If unpatched, **disable** the vulnerable REST API endpoint. π **Mitigate**: Implement strict input validation or use a safe deserialization library. π« **Block**: Restrict network access to the API.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: Immediate patching required. With CVSS High severity and no auth needed, this is a high-priority target for automated attacks.
