Lifecycle Timeline
2DescriptionCVE.org
Sustainable Irrigation Platform (SIP) through version 5.2.16 contains a path traversal vulnerability that allows attackers with access to the restore functionality to write files to arbitrary locations by uploading crafted JSON backup files with unvalidated keys used to construct file paths. Attackers can exploit the lack of key validation in the JSON restore process, combined with the absence of a required passphrase in the default configuration or the default passphrase 'opendoor', to write arbitrary JSON files outside the intended data directory.
AnalysisAI
Arbitrary file write in Sustainable Irrigation Platform (SIP) through 5.2.16 lets remote attackers plant JSON files outside the intended data directory by abusing the JSON backup-restore feature, which builds file paths from attacker-controlled keys without validation. Because the default deployment ships with no required passphrase (or the hardcoded default 'opendoor'), an attacker can reach the restore endpoint without legitimate credentials. Publicly available exploit code exists (VulnCheck / Zero Science advisory), and EPSS/KEV data were not provided, so exploitation appears proof-of-concept rather than confirmed in-the-wild.
Technical ContextAI
SIP is a web-based irrigation management application (CPE cpe:2.3:a:dan-in-ca:sip). The flaw is a classic CWE-22 path traversal (Improper Limitation of a Pathname to a Restricted Directory): the restore routine deserializes an uploaded JSON backup and uses the object's keys directly as filesystem path components. Because those keys are neither sanitized nor constrained to the data directory, traversal sequences (e.g. ../) let the write operation escape the intended folder. The weakness is compounded by an authentication design flaw - the backup/restore protection relies on a passphrase that is empty in the default configuration or set to the well-known default 'opendoor', so the security boundary that should gate the feature is effectively absent out of the box.
RemediationAI
No fixed version was included in the supplied data, so treat this as No vendor-released patch identified at time of analysis and monitor the VulnCheck advisory (https://www.vulncheck.com/advisories/sustainable-irrigation-platform-path-traversal-via-json-backup-restore) and Zero Science advisory (https://www.zeroscience.mk/#/advisories/ZSL-2026-5996) for an upgrade beyond 5.2.16. As immediate compensating controls, set a strong, non-default backup passphrase to replace the empty/'opendoor' default (this alone removes the unauthenticated path but does not fix the traversal for those who know the passphrase), restrict network access to the restore/backup endpoint via firewall rules or a reverse-proxy allowlist so only trusted administrative hosts can reach it, and place the application behind authentication and off the public internet. Where feasible, run the service under a low-privileged account with a read-only or tightly scoped filesystem so a successful traversal cannot overwrite sensitive files outside the data directory; the trade-off is that overly strict filesystem permissions may break legitimate backup restores and require testing.
