| Risk Level | Issue | |------------|-------| | | The file is not from a known official source. No checksum matches any public IKVM release. | | High | 0x0 in version string often appears in malware that zeros out sections of PE headers. | | Medium | May contain vulnerable versions of OpenJDK classes (e.g., old Log4j, deserialization flaws). | | Low | Could be a benign but orphaned build artifact. |
In some cases, the actual file required is iKVM__V1.69.21.0x0.jar.pack.gz . The browser/IPMIView tool needs to unpack this file to make it work. 2. Console Color Issues (X9/X10 Servers) ikvm--v1.69.21.0x0.jar
: Instead of using standard modern web browsers, use the standalone Supermicro IPMIView desktop software utility. IPMIView comes pre-bundled with a master iKVM.jar in its installation directory ( C:\Program Files (x86)\SUPERMICRO\IPMIView\iKVM.jar ), bypassing the need to pull the specific patch file over HTTP. 2. Unsigned JAR / Security Blockages | Risk Level | Issue | |------------|-------| |
When a user logs into a Supermicro IPMI web interface (usually via a web browser) and clicks on "Remote Control" > "Console Redirection," the browser downloads a .jnlp (Java Network Launch Protocol) file. This JNLP file points to the iKVM__V1.69.21.0x0.jar file to launch the viewer application. Key features of this viewer include: Remote display and input control. | | Medium | May contain vulnerable versions
: Build a isolated virtual machine running Windows 7 and an archived version of Java 6 or 7. This bypasses modern security blockades entirely.
Utilize IcedTea-Web for a modern Java Web Start implementation, or configure java.security to enable weaker algorithms (e.g., TLSv1 , 3DES_EDE_CBC ). 3. "No valid certificate" or "Certificate Expired"
