Summary

CVE-2021-48008 is an unauthenticated SQL injection vulnerability in Chanjet CRM, a customer relationship management platform from Chanjet Information Technology Co., Ltd. The flaw exists in the get_usedspace.php endpoint, where the site_id GET parameter is passed into a database query without proper sanitization, allowing a remote, unauthenticated attacker to inject arbitrary SQL. The issue carries a HIGH severity rating (CVSS v4.0 base score 8.7), reflecting its network-exploitable, low-complexity, no-authentication nature.

Technical details

  • Root cause: The site_id parameter supplied via an HTTP GET request to get_usedspace.php is concatenated directly into a backend SQL query without input validation, sanitization, or parameterized queries (CWE-89: Improper Neutralization of Special Elements used in an SQL Command).
  • Trigger conditions: An attacker simply needs network access to the exposed Chanjet CRM get_usedspace.php endpoint; no authentication, user interaction, or special privileges are required.
  • Attack vector: Remote, over the network, using UNION-based SQL injection techniques crafted into the site_id parameter.
  • Impact: Successful exploitation allows an attacker to read and extract sensitive data from the underlying database (confidentiality impact rated High), potentially exposing customer records, credentials, or other business data stored by the CRM.

Affected software

  • Chanjet CRM — all versions (the CVE record does not specify a fixed or bounded version range; the vendor has not published a version-specific advisory).

Severity

  • CVSS v3.1 Base Score: 7.5 (High)
    • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
  • CVSS v4.0 Base Score: 8.7 (High)
    • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: No vendor-published patched version is documented in the public CVE record. Organizations running Chanjet CRM should contact Chanjet Information Technology Co., Ltd. directly to confirm whether a fixed build or hotfix is available for their deployed version.
  • If no patch is available:
    • Restrict network access to the get_usedspace.php endpoint (and the CRM application generally) to trusted internal networks only; do not expose it directly to the internet.
    • Deploy a web application firewall (WAF) rule to detect and block SQL injection patterns targeting the site_id parameter.
    • Monitor web server and database logs for anomalous UNION-based query patterns or unexpected access to get_usedspace.php.
    • Apply the principle of least privilege to the database account used by the CRM application to limit the impact of a successful injection.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
