CVE-2025-58579: Sick Baggage Analytics Auth Bypass Flaw

CVE-2025-58579 Overview

CVE-2025-58579 is an information disclosure vulnerability affecting multiple SICK Analytics products. The affected endpoint lacks authentication controls, allowing unauthenticated remote attackers to query it and enumerate valid user accounts within the application. The weakness is categorized under [CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere].

User enumeration enables adversaries to build target lists for credential stuffing, password spraying, and phishing campaigns against confirmed accounts. The vulnerability affects five SICK Analytics products used in baggage, enterprise, logistic diagnostic, package, and tire analytics workflows.

Critical Impact
Unauthenticated attackers can enumerate valid user accounts across affected SICK Analytics deployments, providing reconnaissance data for follow-on authentication attacks.

Affected Products

SICK Baggage Analytics
SICK Enterprise Analytics
SICK Logistic Diagnostic Analytics
SICK Package Analytics
SICK Tire Analytics

Technical Details for CVE-2025-58579

Vulnerability Analysis

The vulnerability resides in an application endpoint that returns user-related data without enforcing authentication. An unauthenticated attacker who can reach the application over the network can issue requests to this endpoint and receive responses that confirm whether specific user identifiers exist in the system.

User enumeration weaknesses are commonly leveraged as a preparatory step for larger attack chains. By separating valid usernames from invalid ones, attackers reduce the noise generated by brute-force and credential stuffing attempts. This lowers the likelihood of triggering rate-limiting or lockout controls tied to failed authentication attempts on unknown accounts.

Root Cause

The root cause is missing authentication on an application endpoint that exposes user information. The endpoint should require an authenticated session before returning any data that could distinguish valid users from invalid ones. Response differences, such as varying status codes, error messages, or timing, allow attackers to infer account existence.

Attack Vector

Exploitation requires network access to the affected SICK Analytics web application. No privileges and no user interaction are required. An attacker sends crafted requests to the vulnerable endpoint and analyzes the responses to compile a list of valid usernames. The vulnerability affects confidentiality only; integrity and availability are not directly impacted.

The vulnerability is described in prose only; SICK has not published proof-of-concept code. Refer to the SICK CSAF PDF Advisory for vendor technical details.

Detection Methods for CVE-2025-58579

Indicators of Compromise

Repeated HTTP requests from a single source IP to the same user-related endpoint on SICK Analytics applications within a short time window.
Sequential or dictionary-based iteration over username parameters in application access logs.
Anomalous volumes of unauthenticated requests targeting user lookup or account validation endpoints.

Detection Strategies

Enable verbose application logging on SICK Analytics endpoints and forward events to a centralized SIEM for correlation.
Baseline normal request rates for user-facing endpoints and alert on statistical outliers indicative of enumeration.
Deploy a web application firewall (WAF) with rate-limiting rules on unauthenticated endpoints of the SICK Analytics interface.

Monitoring Recommendations

Monitor access logs for high request-per-second rates from single IPs against user-related endpoints.
Track failed authentication follow-ups from IPs that previously queried enumeration-vulnerable endpoints.
Correlate network reconnaissance activity from OT/ICS network segments where SICK Analytics is deployed.

How to Mitigate CVE-2025-58579

Immediate Actions Required

Review the SICK PSIRT Resource and apply the fixed versions specified in the SICK CSAF JSON Advisory.
Restrict network access to SICK Analytics applications so only authorized management hosts and users can reach the web interface.
Enforce rate limiting and IP-based throttling on all user-related endpoints until the patch is applied.

Patch Information

SICK has published advisory sca-2025-0010 with remediation guidance. Administrators should consult the SICK CSAF PDF Advisory for fixed version details and follow the general hardening guidance in the SICK Cybersecurity Guidelines.

Workarounds

Place SICK Analytics behind a reverse proxy or VPN so the application is not reachable from untrusted networks.
Apply the network segmentation and defense-in-depth controls described in CISA ICS Recommended Practices.
Configure the WAF to normalize response codes and messages on user-related endpoints, reducing the signal available to enumeration attempts.

bash

# Example nginx rate-limit and access restriction for SICK Analytics endpoints
limit_req_zone $binary_remote_addr zone=sick_user_lookup:10m rate=5r/m;

server {
    listen 443 ssl;
    server_name analytics.example.local;

    location /api/users/ {
        limit_req zone=sick_user_lookup burst=5 nodelay;
        allow 10.10.20.0/24;   # management subnet
        deny  all;
