Chinese Hackers Have Started Exploiting the Newly Disclosed React2Shell Vulnerability

"Two hacking groups with ties to China have been observed weaponizing the newly disclosed security flaw in React Server Components (RSC) within hours of it becoming public knowledge. The vulnerability in question is CVE-2025-55182 (CVSS score: 10.0), aka React2Shell, which allows unauthenticated remote code execution. It has been addressed in React versions 19.0.1, 19.1.2, and 19.2.1. According to a new report shared by Amazon Web Services (AWS), two China-linked threat actors known as Earth Lamia and Jackpot Panda have been observed attempting to exploit the maximum-severity security flaw."

""Our analysis of exploitation attempts in AWS MadPot honeypot infrastructure has identified exploitation activity from IP addresses and infrastructure historically linked to known China state-nexus threat actors," CJ Moses, CISO of Amazon Integrated Security, said in a report shared with The Hacker News. Specifically, the tech giant said it identified infrastructure associated with Earth Lamia, a China-nexus group that was attributed to attacks exploiting a critical SAP NetWeaver flaw (CVE-2025-31324) earlier this year. The hacking crew has targeted sectors across financial services, logistics, retail, IT companies, universities, and government organizations across Latin America, the Middle East, and Southeast Asia. The attack efforts have also originated from infrastructure related to another China-nexus cyber threat actor known as Jackpot Panda, which has primarily singled out entities that are either engaged in or support online gambling operations in East and Southeast Asia. Jackpot Panda, per CrowdStrike, is assessed to be active since at least 2020, and has targeted trusted third-party relationships in an attempt to deploy malicious implants and gain initial access. Notably, the threat actor was connected to the supply chain compromise of a chat app known as Comm100 in September 2022. The activity is tracked by ESET as Operation ChattyGoblin."

CVE-2025-55182 (React2Shell) is a maximum-severity React Server Components vulnerability that permits unauthenticated remote code execution and carries a CVSS score of 10.0. Patches for the flaw are available in React versions 19.0.1, 19.1.2, and 19.2.1. AWS observed exploitation attempts in its MadPot honeypot from infrastructure historically linked to China state-nexus actors. Identified threat actors include Earth Lamia, previously tied to a critical SAP NetWeaver exploit and active across multiple sectors and regions, and Jackpot Panda, which targets online-gambling-related entities and has a history of supply-chain compromise and third-party targeting.
