Cybersecurity researchers have discovered a new Java-based "sophisticated" information stealer that uses a Discord bot to exfiltrate sensitive data from compromised hosts. The malware, named NS-STEALER, is propagated via ZIP archives masquerading as cracked software, Trellix security researcher Gurumoorthi Ramanathan said in an analysis published last week. The ZIP file contains

An advanced China-nexus cyber espionage group previously linked to the exploitation of security flaws in VMware and Fortinet appliances has been linked to the abuse of a critical vulnerability in VMware vCenter Server as a zero-day since late 2021. "UNC3886 has a track record of utilizing zero-day vulnerabilities to complete their mission without being detected, and this latest example further

Microsoft on Friday revealed that it was the target of a nation-state attack on its corporate systems that resulted in the theft of emails and attachments from senior executives and other individuals in the company's cybersecurity and legal departments. The Windows maker attributed the attack to a Russian advanced persistent threat (APT) group it tracks as Midnight Blizzard (formerly

### Summary [Vite dev server option](https://vitejs.dev/config/server-options.html#server-fs-deny) `server.fs.deny` can be bypassed on case-insensitive file systems using case-augmented versions of filenames. Notably this affects servers hosted on Windows. This bypass is similar to https://nvd.nist.gov/vuln/detail/CVE-2023-34092 -- with surface area reduced to hosts having case-insensitive filesystems. ### Patches Fixed in [email protected], [email protected], [email protected], [email protected] ### Details Since `picomatch` defaults to case-sensitive glob matching, but the file server doesn't discriminate; a blacklist bypass is possible. See `picomatch` usage, where `nocase` is defaulted to `false`: https://github.com/vitejs/vite/blob/v5.1.0-beta.1/packages/vite/src/node/server/index.ts#L632 By requesting raw filesystem paths using augmented casing, the matcher derived from `config.server.fs.deny` fails to block access to sensitive files. ### PoC **Setup** 1. Created vanilla Vite project using `npm c...

This Metasploit module exploit takes advantage of the StringSubstitutor interpolator class, which is included in the Commons Text library. A default interpolator allows for string lookups that can lead to remote code execution. This is due to a logic flaw that makes the script, dns and url lookup keys interpolated by default, as opposed to what it should be, according to the documentation of the StringLookupFactory class. Those keys allow an attacker to execute arbitrary code via lookups primarily using the script key. In order to exploit the vulnerabilities, the following requirements must be met: Run a version of Apache Commons Text from version 1.5 to 1.9, use the StringSubstitutor interpolator, and the target should run JDK versions prior to 15.
