Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical auth bypass in BMC BladeLogic RSCD Agent. π **Consequences**: Attackers can reset ANY user password without proper credentials. Total loss of integrity and access control.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Flaw in the **RPC API** handling of **xmlrpc** action packets.β¦
π¦ **Affected**: BMC BladeLogic Server Automation (BSA). π **Versions**: 8.2.x, 8.3.x, and 8.5.x. π₯οΈ **Platform**: Linux and UNIX based RSCD agents.
Q4What can hackers do? (Privileges/Data)
π **Action**: Remote attackers can **reset arbitrary user passwords**. π **Privilege**: Gains unauthorized access to the automation suite. π **Scope**: Full control over server configuration and management workflows.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: LOW. πͺ **Auth**: Requires NO valid authentication initially. π‘ **Vector**: Remote exploitation via network packets. π― **Ease**: High ease of exploitation due to simple packet injection.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Exploit**: YES. π **Sources**: Exploit-DB (ID: 43939) and PacketStormSecurity. π **Status**: Publicly available PoC/Exploit code exists. β οΈ **Risk**: Active exploitation is highly likely.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for BMC BSA RSCD agents on Linux/UNIX. π‘ **Test**: Send malformed xmlrpc action packets after failed auth. π **Tool**: Use existing PoC scripts from Exploit-DB to verify vulnerability presence.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fix**: YES. π **Official**: BMC released a solution (Knowledge Article kA214000000dBpnCAE). π **Action**: Update to a patched version of BSA immediately. π **Date**: Disclosed June 2016.
Q9What if no patch? (Workaround)
π **Workaround**: If patching is delayed, **block external access** to the RSCD RPC API ports. π« **Network**: Restrict access to trusted IPs only.β¦
π¨ **Priority**: CRITICAL. π΄ **Urgency**: High. π **Impact**: Complete compromise of server automation infrastructure. π **Action**: Patch immediately or isolate the service. Do not ignore this vulnerability.
