Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Wavelink Avalanche allows unlimited uploads of dangerous files. π **Consequences**: Attackers can achieve **Remote Code Execution (RCE)** on the target system. It's a critical security breach!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: The system fails to **limit the number of uploads** for dangerous file types. This lack of restriction is the core flaw allowing the attack vector.
Q3Who is affected? (Versions/Components)
π’ **Affected Vendor**: Ivanti (formerly Wavelink). π¦ **Product**: Wavelink Avalanche. π **Versions**: Version **6.4.1** and all earlier versions are vulnerable.
Q4What can hackers do? (Privileges/Data)
π» **Attacker Capabilities**: Hackers can execute arbitrary code remotely. This grants them full control over the server, potentially leading to data theft or system takeover.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: The description implies **Remote** execution. While specific auth requirements aren't detailed, the ability to upload files often implies access to the upload interface.β¦
π **Public Exploit**: The provided data shows **no public PoC or Exploit** (pocs: []). However, the risk remains high due to the nature of RCE vulnerabilities.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Verify if you are running Wavelink Avalanche version **6.4.1 or older**. Check your server logs for excessive uploads of executable or script files.
Q8Is it fixed officially? (Patch/Mitigation)
β **Official Fix**: Yes! Refer to the **v6.4.2 release notes** from Wavelink/Ivanti. Upgrading to version 6.4.2 or later is the primary mitigation.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: If you cannot upgrade immediately, implement strict **file upload restrictions** and **WAF rules** to block dangerous file types. Limit upload frequency manually.
Q10Is it urgent? (Priority Suggestion)
β‘ **Urgency**: **HIGH**. Since this leads to **RCE**, it is a critical priority. Patch immediately to prevent potential system compromise.
