# AsiaInfo BSS: management API lets unauthenticated attackers create admin accounts

Link for people: https://infrastack.ai/live/CVE-2026-125297 (this .md is for agents)

AsiaInfo Business Support System (BSS) versions 9.2.0 through 9.2.40 accept requests to the management API path /bss/sysmgnt/api/ without authentication. A remote attacker can create an account with administrative privileges or take over existing accounts.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the BSS deployment runs a version from 9.2.0 through 9.2.40 (unknown how the sources expect this to be read from the product itself)
- Look for reachable requests to `/bss/sysmgnt/api/` from outside the trusted network (unknown exact check from the sources)

## Fix

- AsiaInfo BSS: `9.2.41`

## Timeline

- 2026-11-10T22:27:29+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-125297

## From the sources

AsiaInfo Business Support System (BSS) 9.2.0 through 9.2.40 accepts unauthenticated requests via the management API '/bss/sysmgnt/api/'. A remote, unauthenticated attacker could provision a new account with administrative privileges or take over existing accounts, and perform other administrative actions. Fixed in 9.2.41.
