Title

Weaver E-office < 10.0_20221201 Unauthenticated Arbitrary File Read via XmlRpcServlet

Summary

Weaver (Fanwei) E-office versions prior to 10.0_20221201 contain an unauthenticated arbitrary file upload vulnerability in the OfficeServer.php endpoint that allows remote attackers to upload malicious files by sending multipart POST requests with arbitrary filenames and disguised content types. Attackers can upload PHP webshells to the Document directory and execute them via HTTP GET requests to achieve remote code execution as the web server user. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-10-10 (UTC).

CVE-2022-50992 (GCVE-0-2022-50992)

Vulnerability from nvd – Published: 2026-04-30 16:09 – Updated: 2026-04-30 17:30 X_Known Exploited Vulnerability

Title

Weaver E-cology 9.5 Unauthenticated Arbitrary File Read via XmlRpcServlet

Summary

Weaver (Fanwei) E-cology 9.5 versions prior to 10.52 contain an arbitrary file read vulnerability in the XmlRpcServlet interface at the XML-RPC endpoint that allows unauthenticated remote attackers to read arbitrary files by supplying file paths to the WorkflowService.getAttachment and WorkflowService.LoadTemplateProp methods. Attackers can exploit these methods without authentication to retrieve sensitive files including system configuration files and database credentials from the server. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-12-14 (UTC).

CVE-2026-22679 (GCVE-0-2026-22679)

Vulnerability from nvd – Published: 2026-04-07 12:51 – Updated: 2026-05-05 13:39 X_Known Exploited Vulnerability

Title

Weaver E-cology 10.0 Unauthenticated RCE via dubboApi Debug Endpoint

Summary

Weaver (Fanwei) E-cology 10.0 versions prior to 20260312 contain an unauthenticated remote code execution vulnerability in the /papi/esearch/data/devops/dubboApi/debug/method endpoint that allows attackers to execute arbitrary commands by invoking exposed debug functionality. Attackers can craft POST requests with attacker-controlled interfaceName and methodName parameters to reach command-execution helpers and achieve arbitrary command execution on the system. Exploitation evidence was first observed by the Shadowserver Foundation on 2026-03-31 (UTC).

CVE-2022-50992 (GCVE-0-2022-50992)

Vulnerability from cvelistv5 – Published: 2026-04-30 16:09 – Updated: 2026-04-30 17:30 X_Known Exploited Vulnerability

Title

Weaver E-cology 9.5 Unauthenticated Arbitrary File Read via XmlRpcServlet

Summary

Weaver (Fanwei) E-cology 9.5 versions prior to 10.52 contain an arbitrary file read vulnerability in the XmlRpcServlet interface at the XML-RPC endpoint that allows unauthenticated remote attackers to read arbitrary files by supplying file paths to the WorkflowService.getAttachment and WorkflowService.LoadTemplateProp methods. Attackers can exploit these methods without authentication to retrieve sensitive files including system configuration files and database credentials from the server. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-12-14 (UTC).

Title

Weaver E-office < 10.0_20221201 Unauthenticated Arbitrary File Read via XmlRpcServlet

Summary

Weaver (Fanwei) E-office versions prior to 10.0_20221201 contain an unauthenticated arbitrary file upload vulnerability in the OfficeServer.php endpoint that allows remote attackers to upload malicious files by sending multipart POST requests with arbitrary filenames and disguised content types. Attackers can upload PHP webshells to the Document directory and execute them via HTTP GET requests to achieve remote code execution as the web server user. Exploitation evidence was first observed by the Shadowserver Foundation on 2022-10-10 (UTC).

CVE-2026-22679 (GCVE-0-2026-22679)

Vulnerability from cvelistv5 – Published: 2026-04-07 12:51 – Updated: 2026-05-05 13:39 X_Known Exploited Vulnerability

Title

Weaver E-cology 10.0 Unauthenticated RCE via dubboApi Debug Endpoint

Summary

Weaver (Fanwei) E-cology 10.0 versions prior to 20260312 contain an unauthenticated remote code execution vulnerability in the /papi/esearch/data/devops/dubboApi/debug/method endpoint that allows attackers to execute arbitrary commands by invoking exposed debug functionality. Attackers can craft POST requests with attacker-controlled interfaceName and methodName parameters to reach command-execution helpers and achieve arbitrary command execution on the system. Exploitation evidence was first observed by the Shadowserver Foundation on 2026-03-31 (UTC).
