The Chinese-speaking threat actor known as Earth Lusca has been observed using a new backdoor dubbed KTLVdoor as part of a cyber attack targeting an unnamed trading company based in China. The previously unreported malware is written in Golang, and thus is a cross-platform weapon capable of targeting both Microsoft Windows and Linux systems. "KTLVdoor is a highly obfuscated malware that

### Details The `/api/v2/simulation` [POST handler](https://github.com/spectolabs/hoverfly/blob/15d6ee9ea4e0de67aec5a41c28d21dc147243da0/core/handlers/v2/simulation_handler.go#L87) allows users to create new simulation views from the contents of a user-specified file. This feature can be abused by an attacker to read arbitrary files from the Hoverfly server. ```go # https://github.com/spectolabs/hoverfly/blob/15d6ee9ea4e0de67aec5a41c28d21dc147243da0/core/hoverfly_funcs.go#L186 func (hf *Hoverfly) readResponseBodyFile(filePath string) (string, error) { if filepath.IsAbs(filePath) { return "", fmt.Errorf("bodyFile contains absolute path (%s). only relative is supported", filePath) } fileContents, err := ioutil.ReadFile(filepath.Join(hf.Cfg.ResponsesBodyFilesPath, filePath)) if err != nil { return "", err } return string(fileContents[:]), nil } ``` Note that, although the code prevents absolute paths from being specified, an attacker can escape out of the `hf.Cfg.ResponsesB...

The threat of VBA macros has diminished since Microsoft prevented the execution of macros in Microsoft Office documents downloaded from the internet, but not all users are using the latest up-to-date Office versions and can still be vulnerable.

This Metasploit module uses a dictionary to brute force valid usernames from Cerberus FTP server via SFTP. This issue affects all versions of the software older than 6.0.9.0 or 7.0.0.2 and is caused by a discrepancy in the way the SSH service handles failed logins for valid and invalid users. This issue was discovered by Steve Embling.

This Metasploit module exploits an authentication bypass in libssh server code where a USERAUTH_SUCCESS message is sent in place of the expected USERAUTH_REQUEST message. libssh versions 0.6.0 through 0.7.5 and 0.8.0 through 0.8.3 are vulnerable. Note that this modules success depends on whether the server code can trigger the correct (shell/exec) callbacks despite only the state machines authenticated state being set. Therefore, you may or may not get a shell if the server requires additional code paths to be followed.

This Metasploit module scans for the Juniper SSH backdoor (also valid on Telnet). Any username is required, and the password is <<< %s(un=%s) = %u.

This Metasploit module exploits a default misconfiguration flaw on Apache Karaf versions 2.x-4.x. The karaf user has a known default password, which can be used to login to the SSH service, and execute operating system commands from remote.

Eaton Power Xpert Meters running firmware below version 12.x.x.x or below version 13.3.x.x ship with a public/private key pair that facilitate remote administrative access to the devices. Tested on: Firmware 12.1.9.1 and 13.3.2.10.

This Metasploit module uses a malformed packet or timing attack to enumerate users on an OpenSSH server. The default action sends a malformed (corrupted) SSH_MSG_USERAUTH_REQUEST packet using public key authentication (must be enabled) to enumerate users. On some versions of OpenSSH under some configurations, OpenSSH will return a "permission denied" error for an invalid user faster than for a valid user, creating an opportunity for a timing attack to enumerate users. Testing note: invalid users were logged, while valid users were not. YMMV.

This Metasploit module scans for the Fortinet SSH backdoor.
