Description
Path Traversal vulnerability in Frenify Arlo allows PHP Local File Inclusion. This issue affects Arlo: from n/a through 6.0.3.
Analysis
Path Traversal vulnerability enabling PHP Local File Inclusion (LFI) in Frenify Arlo through version 6.0.3. The vulnerability allows unauthenticated remote attackers to read arbitrary files from the server filesystem by manipulating path parameters, potentially exposing sensitive configuration files, source code, and credentials. With a CVSS score of 8.1 and network-accessible attack vector, this vulnerability poses significant risk to confidentiality and integrity; exploitation likelihood and active weaponization status cannot be confirmed from available data, but the straightforward nature of path traversal attacks suggests moderate-to-high real-world exploitation probability.
Technical Context
The vulnerability stems from improper input validation in file inclusion mechanisms within Frenify Arlo (affected CPE likely: cpe:2.3:a:frenify:arlo:*:*:*:*:*:*:*:*). CWE-35 (Path Traversal) indicates the application fails to properly sanitize or validate user-supplied path parameters before using them in file operations. In PHP applications, this typically manifests through include(), require(), file_get_contents(), or similar functions that process user input without adequate canonicalization or directory restriction. The LFI nature suggests attackers can traverse directory hierarchies using sequences like '../' or null bytes to access files outside the intended web root or application directory, potentially including /etc/passwd, application configuration files, or database credentials stored in plaintext configuration scripts.
Affected Products
Arlo (6.0.3 and earlier (up to version 6.0.3 inclusive)
Remediation
- priority: CRITICAL; action: Upgrade Frenify Arlo to version 6.0.4 or later; details: Vendor has released patches addressing path traversal input validation. Immediate upgrade is recommended for all instances running version 6.0.3 or earlier. - priority: HIGH; action: Implement Web Application Firewall (WAF) rules; details: Deploy WAF signatures to block common path traversal patterns (../, ..\, %2e%2e, null bytes, unicode encodings) in HTTP requests to Arlo endpoints prior to patching. - priority: HIGH; action: Restrict network access; details: Limit access to Arlo application to trusted networks or require VPN/IP whitelisting until patches can be applied; disable public internet exposure if operationally feasible. - priority: MEDIUM; action: File permission hardening; details: Restrict file system permissions on sensitive configuration files (/etc/passwd, application config files, .env, database credentials) to prevent disclosure via LFI even if path traversal succeeds. - priority: MEDIUM; action: Log and monitor for exploitation; details: Enable detailed logging of file inclusion requests and monitor for patterns consistent with directory traversal attempts (../ sequences, unusual file paths in request parameters).
