Title
Security advisory: Authenticated RCE (second-order SQL injection) in Lansweeper 12.2.1.0 (web reports 12.2.1.6) (Lansweeper)
Summary
0day Rubbish Research Team is publicly disclosing a vulnerability in Lansweeper 12.2.1.0 (web reports 12.2.1.6)
(Lansweeper). The research is published and a proof-of-concept is available.
Authenticated RCE (second-order SQL injection) (CVSS 8.8, authenticated)
Lansweeper 12.2.1.0 contains a second-order SQL injection in the LicenseActions console. A SQL Server sub-server name
containing a single quote is stored and later concatenated unescaped into a NOT LIKE clause; the query is executed with
stacked statements, enabling EXEC xp_cmdshell. The default lansweeperuser database account is SQL Server sysadmin and
xp_cmdshell is enabled by default, so an authenticated administrator achieves remote code execution. Dynamically
verified.
Impact: Full compromise of the Lansweeper server. The attacker can execute arbitrary commands, read scanned asset and
credential data, and pivot into the managed network.

Vendor has been notified. CVE ID is pending.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
