A remote attacker can send a crafted request to /tplus/ajaxpro/Ufida.T.CodeBehind._PriorityLevel,App_Code.ashx?method=GetStoreWarehouseByStore with a malicious JSON body that leverages deserialization of attacker-controlled .NET types to invoke arbitrary methods such as System.Diagnostics.Process.Start. This can result in execution of arbitrary commands in the context of the T+ application service account. Exploitation evidence was observed by the Shadowserver Foundation as early as 2023-08-19 (UTC).","published_at":"2026-01-15T21:44:58.843000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":9.3,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"CRITICAL","ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":true,"ssvc_technical_impact":"total","cwes":["CWE-502"],"nvd_references":["https://www.chanjetvip.com/product/goods/detail?id=6077e91b70fa071069139f62","https://www.freebuf.com/articles/web/381731.html","https://blog.csdn.net/qq_53003652/article/details/134031230","https://blog.csdn.net/u010025272/article/details/131553591","https://github.com/MD-SEC/MDPOCS/blob/main/ChangJieTongTPlus_GetStoreWarehouseByStore_Rce_Poc.py","https://www.vulncheck.com/advisories/changjetong-tplus-getstorewarehousebystore-deserialization-rce"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:45:52.776364Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"changjetong-information-technology-co.-ltd.","vendor_name":"Changjetong Information Technology Co., Ltd.","product_slug":"t","product_name":"T+","version_start":"0","version_start_inclusive":true,"version_end":"16.*","version_end_inclusive":true,"cpe23_uri":"cve5:changjetong-information-technology-co.-ltd.:t:0:16.*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.chanjetvip.com/product/goods/detail?id=6077e91b70fa071069139f62","source_type":"MISC","tags":[]},{"url":"https://www.freebuf.com/articles/web/381731.html","source_type":"MISC","tags":[]},{"url":"https://blog.csdn.net/qq_53003652/article/details/134031230","source_type":"MISC","tags":[]},{"url":"https://blog.csdn.net/u010025272/article/details/131553591","source_type":"MISC","tags":[]},{"url":"https://github.com/MD-SEC/MDPOCS/blob/main/ChangJieTongTPlus_GetStoreWarehouseByStore_Rce_Poc.py","source_type":"MISC","tags":[]},{"url":"https://www.vulncheck.com/advisories/changjetong-tplus-getstorewarehousebystore-deserialization-rce","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-01-15T21:44:58.843000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:32:03.531962Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:32:03.531962Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:32:03.531962Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:45:52.776364Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:45:52.776364Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:45:52.776364Z","label":"SSVC decision revised","source":"vulnrichment"}]}
