This vulnerability stems from improper neutralization of special elements used in a command, which could enable an unauthorized attacker to perform spoofing attacks over a network. This allows an attacker to potentially masquerade as a legitimate service or user, leading to unauthorized access or information disclosure. The vulnerability was published by Microsoft on 2026-05-07 and affects the Azure Cloud Shell platform. Defenders need to implement detections and mitigations to prevent exploitation of this vulnerability and protect against potential spoofing attacks.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a command injection point in Azure Cloud Shell.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious command string containing special elements (e.g., shell metacharacters) designed to be improperly neutralized.\u003c/li\u003e\n\u003cli\u003eThe crafted command is injected into the vulnerable Azure Cloud Shell application through a network request.\u003c/li\u003e\n\u003cli\u003eAzure Cloud Shell processes the injected command without proper sanitization.\u003c/li\u003e\n\u003cli\u003eThe injected command executes, leading to the attacker\u0026rsquo;s desired outcome, such as network spoofing.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the spoofing capability to impersonate a trusted entity on the network.\u003c/li\u003e\n\u003cli\u003eThe attacker intercepts network traffic or gains unauthorized access to resources.\u003c/li\u003e\n\u003cli\u003eThe attacker exfiltrates sensitive data or performs malicious actions under the guise of the spoofed identity.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-35428 can allow attackers to perform network spoofing attacks within Azure Cloud Shell environments.
