CVE-2022-37940
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 · uneditedPotential security vulnerabilities have been identified in the HPE FlexFabric 5700 Switch Series. These vulnerabilities could be remotely exploited to allow host header injection and URL redirection. HPE has made the following software to resolve the vulnerability in HPE FlexFabric 5700 Switch Series version R2432P61 or later.
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 · moderate confidenceHPE FlexFabric 5700 Switch Series contains vulnerabilities allowing remote exploitation via host header injection and URL redirection. These web-based vulnerabilities can be exploited to manipulate HTTP requests and redirect users to attacker-controlled URLs, potentially leading to phishing attacks or credential theft.

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 the device modelExecute command 'display device' or 'display device manuinfo' via console/SSH to confirm the switch is an HPE FlexFabric 5700 series model (either 40XG 2QSFP+ or 48G 4XG 2QSFP+ variants)Affected if Device is not an HPE FlexFabric 5700 series switch - different models are not affected by this specific CVE
-
Check the installed firmware versionExecute command 'display version' via console/SSH to retrieve the current firmware version installed on the switchAffected if Unable to retrieve firmware version - cannot determine vulnerability status
-
Compare firmware version against R2432P61Examine the version string from 'display version' output. Compare numerically and alphanumerically against R2432P61 (for example, R2432P60, R2432P50, or earlier releases are below R2432P61)Affected if Firmware version is less than R2432P61 (for example, R2432P60, R2432P50, R2432P01, R2431xxx, etc.) - the switch is affected by the host header injection and URL redirection vulnerabilities
User is affected if the device is an HPE FlexFabric 5700 40XG 2QSFP+ or 48G 4XG 2QSFP+ switch running firmware version earlier than R2432P61.

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.
dbcve · scopedUpgrade HPE FlexFabric 5700 Switch Series to version R2432P61 or later to resolve the host header injection and URL redirection vulnerabilities.
R2432P61
- Obtain the R2432P61 firmware or later from support.hpe.com for your specific FlexFabric 5700 switch model
- Review HPE's firmware upgrade documentation for the FlexFabric 5700 Series
- Back up the current switch configuration
- Upload the new firmware to the switch
- Reboot the switch to apply the new firmware
- Verify the firmware version is R2432P61 or later after upgrade
