CVE-2025-54322
Published: 27 December 2025
Description
Xspeeder SXZOS through 2025-12-26 allows root remote code execution via base64-encoded Python code in the chkid parameter to vLogin.py. The title and oIP parameters are also used.
Mitigating Controls (NIST 800-53 r5)AI
Requires validation of untrusted inputs like the base64-encoded chkid parameter to prevent improper neutralization leading to remote code execution.
Mandates timely identification, reporting, and patching of the specific flaw in vLogin.py that enables unauthenticated root RCE.
Provides vulnerability scanning to identify code injection flaws like CWE-94/95 in the affected Xspeeder SXZOS application.
Security SummaryAI
CVE-2025-54322 is a critical root remote code execution vulnerability affecting Xspeeder SXZOS through version 2025-12-26. The flaw exists in the vLogin.py script, where attackers can supply base64-encoded Python code via the chkid parameter, with the title and oIP parameters also utilized in the exploitation process. It carries a CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) and maps to CWE-95 (improper neutralization of directives in dynamically evaluated code) and CWE-94 (improper control of generation of code).
The vulnerability enables unauthenticated remote exploitation over the network with low complexity and no user interaction required. Any remote attacker can trigger it to achieve root-level code execution on the target system, resulting in complete compromise with high impacts to confidentiality, integrity, and availability, including potential scope expansion.
