Vulnerability Description

OpenWrt luci-app-bmx7 before commit 5890760a454dad2cb00389dba2cdc5e779e0ffdd contains a path traversal vulnerability in the bmx7-info CGI script that allows unauthenticated attackers to read files outside the configured runtimeDir. Attackers can supply directory traversal sequences in the query string to escape the intended directory and read sensitive files accessible to the CGI process.

  1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (340007 , 344360 , 347009 , 390709 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

  2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

    • Affected versions: openwrt luci versions earlier than 5890760a454dad2cb00389dba2cdc5e779e0ffdd.
    • Versions reported unaffected: openwrt luci version 5890760a454dad2cb00389dba2cdc5e779e0ffdd.
    • Recommended upgrade: Upgrade openwrt luci to 5890760a454dad2cb00389dba2cdc5e779e0ffdd or later.

  3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
