Vulnerability Details
The official description of CVE-2026-0805 states that it is an input neutralization vulnerability in the Backup Configuration component of Crafty Controller. This vulnerability allows a remote, authenticated attacker to perform file tampering and remote code execution via path traversal. The vulnerability has a CVSS score of 8.2, categorized as high severity, indicating significant potential for exploitation.
The affected product is Crafty Controller, with versions ranging from 4.5.0 to 4.8.0 being vulnerable. The vulnerability is classified under CWE-22, which pertains to improper restriction of a pathname to a restricted directory ('path traversal').
Technical Analysis
The root cause of CVE-2026-0805 lies in the insufficient input validation within the Backup Configuration component. Attackers can exploit this vulnerability through a network by sending specially crafted requests to the affected application, bypassing security controls. The attack complexity is rated as high, meaning that successful exploitation may require specific conditions to be met.
The privileges required for exploitation are low, as an attacker needs only authenticated access to the system. No user interaction is required, which raises the vulnerability's risk profile. The attack can compromise confidentiality and integrity, as attackers can manipulate sensitive files and execute arbitrary code.
The impacts on confidentiality and integrity are rated high, indicating that sensitive data could be accessed and modified without authorization. The availability impact is none, meaning the exploitation does not directly affect system uptime or availability.
