CVE-2021-26572
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 webgetactivexcfg 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 webgetactivexcfg function in HPE Apollo 70 System Baseboard Management Controller (BMC) firmware prior to version 3.0.14.0. The overflow occurs when processing input in the web configuration function, allowing a local attacker with access to the BMC to potentially execute arbitrary code or cause denial of service by overflowing a fixed-size buffer.

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.
-
Identify HPE Apollo 70 System BMC firmware versionAccess BMC web interface and navigate to the firmware version information page, or use IPMI command 'ipmitool -I lanplus -H <bmc_ip> -U <user> -P <pass> mc info', or query Redfish API endpoint /redfish/v1/Managers/1Affected if The firmware version displayed is less than 3.0.14.0
-
Confirm BMC model is HPE Apollo 70 SystemCheck BMC identification via IPMI 'ipmitool -I lanplus -H <bmc_ip> -U <user> -P <pass> mc guid' or via Redfish API /redfish/v1/Managers/1Affected if The system is identified as HPE Apollo 70 System Baseboard Management Controller
-
Verify libifc.so library exists on BMCAccess BMC via SSH or file browser and locate the library file: find / -name 'libifc.so' or check common library paths like /usr/lib/Affected if The vulnerable library libifc.so is present on the BMC filesystem
-
Confirm web management interface is accessibleTest BMC web interface connectivity on ports 80 or 443, or verify HTTP/HTTPS service is running via BMC network protocol settingsAffected if The BMC web interface is enabled and reachable on the network
The environment is affected if it is an HPE Apollo 70 System with BMC firmware version lower than 3.0.14.0, where the vulnerable libifc.so library exists and the web configuration feature is accessible.

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 to remediate this vulnerability. Since this is a local attack requiring BMC access, ensure proper physical security and restrict BMC network access.
