CVE-2021-47782 is a high-severity SQL Injection (CWE-89) vulnerability in Odine Solutions GateKeeper (inferred from references). Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 32.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2021-47782 is a SQL injection vulnerability (CWE-89) affecting Odine Solutions GateKeeper 1.0, specifically in the trafficCycle API endpoint. The flaw allows remote attackers to inject malicious database queries into the PostgreSQL backend by sending crafted payloads to the /rass/api/v1/trafficCycle/ endpoint. It has a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact with low integrity impact and no availability disruption.
Unauthenticated remote attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By crafting and submitting malicious payloads to the vulnerable endpoint, attackers can manipulate database queries to extract sensitive information from the PostgreSQL database.
Advisories and references include a proof-of-concept exploit on Exploit-DB (exploit 50381), a detailed advisory from VulnCheck on the Odine Solutions GateKeeper trafficCycle SQL injection, and the vendor's GateKeeper product page. Security practitioners should consult these sources for any available patches or mitigation guidance.
