Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Weak password change mechanism in Ruijie ReyeeOS. <br>๐ฅ **Consequences**: High risk of unauthorized access, data theft, and service disruption.โฆ
๐ก๏ธ **Root Cause**: CWE-640 (Weak Password Change Procedure). <br>๐ **Flaw**: The system fails to enforce strong validation when users change passwords, allowing predictable or weak credentials.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: Ruijie Networks ReyeeOS. <br>๐ **Versions**: 2.206.x up to (but not including) 2.320.x. <br>๐ข **Vendor**: Ruijie Networks (China).
Q4What can hackers do? (Privileges/Data)
๐ฎ **Privileges**: Attackers can gain unauthorized access. <br>๐ **Data**: High risk of Confidentiality (C:H) and Integrity (I:H) loss. <br>โ ๏ธ **Impact**: Can potentially control the router and compromise network traffic.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: Low. <br>๐ **Network**: Attack Vector is Network (AV:N). <br>๐ **Auth**: No Privileges Required (PR:N). <br>๐ค **UI**: No User Interaction Needed (UI:N). <br>โ **Ease**: Easy to exploit (AC:L).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exploit**: No PoC available in the data. <br>๐ **Wild Exploitation**: Currently unknown. <br>โ ๏ธ **Risk**: Despite no public code, the low exploitation complexity makes it highly dangerous.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Verify if your device runs ReyeeOS version 2.206.x - 2.319.x. <br>๐ก **Scanning**: Check for open management interfaces. <br>๐ **Audit**: Review password policies for weak change mechanisms.
Q8Is it fixed officially? (Patch/Mitigation)
๐ ๏ธ **Fix**: Upgrade to version 2.320.x or later. <br>๐ฅ **Source**: Official Ruijie Networks update. <br>๐ **Reference**: CISA Advisory ICSA-24-338-01.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is delayed, enforce strict manual password policies. <br>๐ **Mitigation**: Restrict network access to the management interface.โฆ
๐ฅ **Urgency**: HIGH. <br>๐ฏ **Priority**: Immediate patching recommended. <br>โก **Reason**: Critical CVSS score, no auth required, and easy exploitation make this a top-priority fix for affected routers.
