CVE-2026-58477 Overview
CVE-2026-58477 is a mass assignment vulnerability [CWE-915] affecting the Dan-in-ca Sustainable Irrigation Platform (SIP) through version 5.2.16. Unauthenticated attackers can supply arbitrary parameter names in HTTP requests to overwrite sensitive configuration settings. Exploitable parameters include the application passphrase and listening port. The absence of adequate request validation also enables the same result through cross-site request forgery (CSRF). The flaw is remotely exploitable over the network, requires no privileges, and needs no user interaction.
Critical Impact
Unauthenticated attackers can overwrite sensitive SIP configuration values, including the passphrase and listening port, resulting in full compromise of platform integrity.

Technical Details for CVE-2026-58477
Vulnerability Analysis
The Sustainable Irrigation Platform binds HTTP request parameters directly to internal configuration objects without an allowlist of writable fields. This design pattern, known as mass assignment [CWE-915], lets a remote client name any internal property in a request body or query string. The server then commits that value to its configuration store.
Sensitive fields exposed through this mechanism include the platform passphrase and the listening port. An attacker who overwrites the passphrase gains administrative control of the deployment. An attacker who alters the listening port can disrupt service availability or redirect traffic. The flaw does not require authentication, and request validation is absent.
Root Cause
The root cause is the assignment of externally controlled properties to protected configuration fields without a server-side allowlist or type check. There is also no anti-CSRF token or origin validation on the state-changing endpoints, so the same modification can be triggered from a victim's browser session.
Attack Vector
An attacker sends a crafted HTTP request that includes parameter names matching internal configuration attributes. Because the endpoint accepts unauthenticated input and lacks CSRF protection, delivery can occur through a direct HTTP call or through a malicious page loaded by a network-adjacent operator. The vulnerability manifests when the platform processes the request and persists attacker-supplied values into its configuration state. See the VulnCheck Security Advisory and Zero Science Advisory ZSL-2026-5997 for technical details.
Detection Methods for CVE-2026-58477
Indicators of Compromise
- Unexpected changes to the SIP passphrase or listening port in the running configuration.
- HTTP POST or GET requests to SIP configuration endpoints containing parameter names such as passphrase, port, or other internal attributes from unauthenticated clients.
- Session or platform restarts correlated with configuration-write requests originating from external IP addresses.
- Outbound requests to SIP from browsers of authenticated operators referred by untrusted origins, indicating possible CSRF delivery.
Detection Strategies
- Inspect web server and reverse proxy logs for requests that supply parameters matching SIP internal configuration fields.
- Deploy web application firewall (WAF) rules that block requests containing reserved configuration parameter names on unauthenticated endpoints.
- Compare current SIP configuration against a known-good baseline on a scheduled interval and alert on drift.
Monitoring Recommendations
- Forward SIP application logs and reverse-proxy access logs to a centralized SIEM for correlation.
- Alert on repeated 200 responses to configuration endpoints from clients without valid session cookies.
- Monitor for parameter tampering patterns and unauthenticated writes to /config or equivalent SIP routes.
How to Mitigate CVE-2026-58477
Immediate Actions Required
- Restrict network access to the SIP management interface to trusted management networks only.
- Place SIP behind a reverse proxy that enforces authentication and strips unknown parameters on state-changing endpoints.
- Rotate the SIP passphrase and audit the current configuration for unauthorized modifications.
- Review web server logs for prior exploitation attempts against configuration endpoints.
Patch Information
No vendor patch is referenced in the advisories for CVE-2026-58477 at the time of publication. Operators should track the VulnCheck Security Advisory and the Zero Science Advisory ZSL-2026-5997 for fixed-version information.
Workarounds
- Block unauthenticated HTTP access to SIP configuration endpoints at the network or reverse-proxy layer.
- Enforce a parameter allowlist at a WAF or proxy so requests carrying fields such as passphrase or port are rejected on public endpoints.
- Require anti-CSRF tokens and a strict SameSite=Strict policy on session cookies for any operator browser sessions used to manage SIP.
- Isolate the irrigation controller on a segmented VLAN with egress filtering to limit exposure to browser-driven CSRF payloads.
