CVE-2021-25169
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Baseboard Management Controller (BMC) firmware in HPE Apollo 70 System prior to version 3.0.14.0 has a local buffer overflow in libifc.so websetservicecfg function.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA local buffer overflow vulnerability exists in the libifc.so library's websetservicecfg function within HPE Apollo 70 System Baseboard Management Controller (BMC) firmware versions prior to 3.0.14.0. An authenticated local attacker could exploit this buffer overflow to potentially execute arbitrary code or cause a denial of service condition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check BMC firmware versionAccess the HPE Apollo 70 System BMC web interface or CLI (via IPMI or Redfish) and retrieve the current firmware version. In the BMC web UI, this is typically found under 'Maintenance' or 'Firmware Information'. Via CLI, use 'ipmitool -I lanplus -H <BMC_IP> -U <user> -P <pass> raw command' or check via Redfish endpoint '/redfish/v1/Managers/Self'Affected if The displayed firmware version is below 3.0.14.0 (e.g., 3.0.13.0, 3.0.12.0, etc.)
-
Verify BMC accessibilityConfirm that the BMC web interface or IPMI/Redfish API is reachable on the HPE Apollo 70 System. The vulnerability requires authenticated local access to the BMC.Affected if The BMC is accessible and you can authenticate to it, but the firmware version is below 3.0.14.0
-
Identify vulnerable component presenceThe vulnerability exists in the libifc.so library's websetservicecfg function within the BMC firmware. This function handles web service configuration. In firmware versions below 3.0.14.0, this component contains the buffer overflow vulnerability.Affected if You are running HPE Apollo 70 System BMC firmware prior to version 3.0.14.0, meaning the vulnerable libifc.so library with the websetservicecfg function is present
You are affected if your HPE Apollo 70 System Baseboard Management Controller is running firmware version lower than 3.0.14.0 and is accessible for authenticated local users to interact with the websetservicecfg function in libifc.so.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data3.0.14.0
Upgrade the HPE Apollo 70 System BMC firmware to version 3.0.14.0 or later. As this is a BMC firmware update, ensure proper planning, backup, and testing procedures are followed to avoid rendering the system inoperable.
