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 · unedited
Stack-based buffer overflow vulnerabilities exist in several underlying management service components accessed through the command-line interface of the AOS-8 and AOS-10 Operating Systems. An authenticated attacker with administrative privileges could exploit these vulnerabilities by sending specially crafted requests to the affected services. Successful exploitation could allow the attacker to execute arbitrary code with elevated privileges on the underlying operating system.

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 confidence

Stack-based buffer overflow vulnerabilities exist in multiple management service components accessed via the CLI of Aruba AOS-8 and AOS-10 operating systems. An authenticated attacker with administrative privileges can send specially crafted requests to trigger the overflow, achieving arbitrary code execution with elevated (root) privileges on the underlying OS.

MitigationApply vendor-provided patches for AOS-8 and AOS-10 once available. Until then, limit CLI access to trusted, administrative users only and monitor for signs of exploitation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed ArubaOS version
    Execute 'show version' or 'show system info' from the CLI and note the software version number
    Affected if The version falls within >= 6.5.4.0 and < 8.10.0.22, OR >= 8.11.0.0 and < 8.12.0.7, OR >= 8.13.0.0 and < 8.13.1.2, OR >= 10.4.0.0 and < 10.4.1.11, OR >= 10.5.0.0 and < 10.7.2.3
  2. Identify installed SD-WAN version
    Execute 'show version' or 'show sd-wan version' from the CLI and note the software version number
    Affected if The version is >= 8.6.0.4-2.2.0.0 and <= 8.6.0.4-2.2.0.7, OR >= 8.7.0.0-2.3.0.0 and <= 8.7.0.0-2.3.0.9
  3. Verify management access configuration
    Execute 'show management' or review the running configuration for management service settings (HTTP/HTTPS/SSH/Telnet) and which interfaces/IPs are permitted
    Affected if The CLI management interface is accessible from untrusted networks or the management VLAN is not properly isolated
  4. Confirm administrative user access
    Execute 'show privilege' or 'show user' to list administrative accounts and their privilege levels
    Affected if Multiple administrative accounts exist with root-level privileges, especially any unexpected or unrecognized accounts

Your environment is affected if the installed ArubaOS or SD-WAN version matches any of the affected ranges AND the CLI is accessible to authenticated administrative users.

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.

Upgrade available Upgrade to 8.10.0.22 / 8.12.0.7 / 8.13.1.2 or later
Fixed in 8.10.0.228.12.0.78.13.1.2
Interim mitigation

Apply vendor-provided patches for AOS-8 and AOS-10 once available. Until then, limit CLI access to trusted, administrative users only and monitor for signs of exploitation.

Recommended fix Moderate confidence

ArubaOS: 8.10.0.22 (for legacy 6.5-8.9 branch), 8.12.0.7 (for 8.11 branch), 8.13.1.2 (for 8.13 branch), or 10.4.1.11 (for 10.4 branch) | SD-WAN: >8.6.0.4-2.2.0.7 or >8.7.0.0-2.3.0.9

  1. Identify the current ArubaOS or SD-WAN version by running 'show version' in the CLI
  2. Determine which version branch your current installation falls into (6.5.x-8.9.x, 8.10.x, 8.11.x, 8.13.x, or 10.4.x for ArubaOS; 8.6.x or 8.7.x for SD-WAN)
  3. For ArubaOS 6.5.4.x through 8.9.x: Plan upgrade to minimum fixed version 8.10.0.22
  4. For ArubaOS 8.11.x: Plan upgrade to minimum fixed version 8.12.0.7
  5. For ArubaOS 8.13.x: Plan upgrade to minimum fixed version 8.13.1.2
  6. For ArubaOS 10.4.x: Plan upgrade to minimum fixed version 10.4.1.11
  7. For SD-WAN 8.6.0.4-2.2.x: Upgrade to a version newer than 8.6.0.4-2.2.0.7
  8. For SD-WAN 8.7.0.0-2.3.x: Upgrade to a version newer than 8.7.0.0-2.3.0.9
Caveat Major version jumps (e.g., ArubaOS 8.x to 10.x) may introduce behavioral or configuration changes - review release notes and migration guides on support.hpe.com before upgrading
