CVE-2021-26996
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 · uneditedE-Series SANtricity OS Controller Software 11.x versions prior to 11.70.1 are susceptible to a vulnerability which when successfully exploited could allow a remote attacker to discover system configuration and application information which may aid in crafting more complex attacks.
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 confidenceE-Series SANtricity OS Controller Software versions 11.x prior to 11.70.1 contains an information disclosure vulnerability allowing remote unauthenticated attackers to discover system configuration and application details. This reconnaissance capability could expose sensitive infrastructure details useful for planning further attacks.

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.
-
Locate the installed SANtricity OS versionAccess the SANtricity System Manager or use the command-line interface (CLI) to retrieve the current OS Controller Software version. This is typically found in the system information or About section of the management interface.Affected if The displayed version falls within the range 11.0.0 to 11.70.1 (excluding 11.70.1).
-
Compare version against the affected rangeTake the installed version number you retrieved and verify whether it is greater than or equal to 11.0.0 AND less than 11.70.1. Any version meeting both conditions is considered affected.Affected if The version meets both conditions: version >= 11.0.0 AND version < 11.70.1.
-
Assess network exposure of the management interfaceDetermine whether the SANtricity management interface (typically ports 8443 or 8080 for web-based access) is exposed to untrusted networks or the internet. Review firewall rules, VLAN configurations, and access control lists.Affected if The management interface is accessible from untrusted networks without proper access restrictions.
-
Review access logs for unauthorized reconnaissanceExamine SANtricity access logs and system logs for evidence of unauthenticated requests that may have queried system configuration, application details, or infrastructure information. Look for repeated queries from external IP addresses.Affected if Unauthenticated external requests attempting to enumerate system configuration details are present in the logs.
You are affected if your SANtricity OS Controller Software version is 11.0.0 or higher but lower than 11.70.1, and the management interface is accessible to unauthenticated remote attackers.
