Authorization Bypass Through User-Controlled Key vulnerability in TMT Lockcell allows Authentication Abuse, Authentication Bypass.
This issue affects Lockcell: before 15.
CVE-2023-3048 is a critical authorization bypass in TMT Lockcell before version 15. A remote, unauthenticated attacker may be able to abuse user-controlled identifiers to access or manipulate data without proper permission checks. Treat internet-facing or sensitive Lockcell deployments as high priority for review.
Executive priority
High priority if Lockcell is deployed. The vulnerability scores critical and may allow unauthenticated authorization bypass with major business impact. Prioritize inventory, version validation, access restriction, and upgrade planning.
Technical view
The CVE describes CWE-639, Authorization Bypass Through User-Controlled Key, affecting TMT Lockcell before 15. CVSS 3.1 is 9.8: network attack vector, low complexity, no privileges, no user interaction, with high confidentiality, integrity, and availability impact. Public references include government advisories and a technical write-up.
Likely exposure
Organizations running TMT Lockcell versions before 15 are potentially exposed, especially if the application is reachable from untrusted networks. The provided data does not identify specific deployment modes, modules, or default configurations.
Exploitation context
The CVE is not listed in KEV in the provided bundle. A public technical reference is tagged as exploit-related, but the sources provided do not establish confirmed active exploitation in the wild.
Researcher notes
Evidence is limited to the CVE record and cited advisories. The source bundle states Lockcell before 15 is affected, but does not provide detailed exploit mechanics, affected configurations, or a full vendor remediation bulletin. Avoid assuming active exploitation without additional evidence.
Mitigation direction
Identify all TMT Lockcell deployments and their versions.
Move Lockcell systems off versions before 15, following vendor or government guidance.
Restrict external access to Lockcell until remediation is complete.
Review authentication and authorization controls around sensitive Lockcell functions.
Monitor vendor, USOM, and national advisory pages for updated instructions.
Validation and detection
Confirm no production Lockcell instance runs a version before 15.
Check asset inventories, CMDB, and application ownership records for Lockcell.
Review access logs for unusual object access or authentication bypass patterns.
Validate that authorization checks are enforced server-side.
Document remediation status and compensating controls for each instance.

CWE-639: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
The CVE wording references privilege impact, so privilege escalation and authorization behavior review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
