#ssh

### Summary * When an attacker obtains the backend login path of RatPanel (including but not limited to weak default paths, brute-force cracking, etc.), they can execute system commands or take over hosts managed by the panel **without logging in**. * In addition to this **remote code execution (RCE) vulnerability**, the flawed code also leads to **unauthorized access**. ### Details In Go, `r.URL.Path` retrieves the part of the URL that comes after the port and before the query parameters or anchor symbols. For example, in the URL `http://localhost:8080/api/ws/ssh?id=1`, the retrieved path would be `/api/ws/ssh`. However, if the request is made to `http://localhost:8080//api/ws/ssh?id=1`, the parsed `r.URL.Path` would be `//api/ws/ssh`. RatPanel uses the `CleanPath` middleware provided by `github.com/go-chi/chi` package to clean URLs, The route path inside the chi router will be cleaned to `/api/ws/ssh`, but this middleware does not process `r.URL.Path`, so the path is still `//a...

### Summary The channel window adjust message of the SSH protocol is used to track the free space in the receive buffer of the other side of a channel. The current implementation takes the value from the message and adds it to an internal state value. This can result in a integer overflow. If the Rust code is compiled with overflow checks, it will panic. A malicious client can crash a server. ### Details According https://datatracker.ietf.org/doc/html/rfc4254#section-5.2, The value must not overflow. The incorrect handling is done in server/encrypted.rs and client/encrypted.rs in the handling of CHANNEL_WINDOW_ADJUST. ``` let amount = map_err!(u32::decode(&mut r))?; ... channel.recipient_window_size += amount; ``` It could be replaced with something like ``` if let Some(ref mut channel) = enc.channels.get_mut(&channel_num) { // rfc 4254: The window MUST NOT be increased above 2^32 - 1 bytes. new_size = channel.recipient_window...

Cybersecurity researchers have flagged a previously undocumented Linux backdoor dubbed Plague that has managed to evade detection for a year. "The implant is built as a malicious PAM (Pluggable Authentication Module), enabling attackers to silently bypass system authentication and gain persistent SSH access," Nextron Systems researcher Pierre-Henri Pezier said. Pluggable Authentication Modules

### Project Address: Project Address [1Panel](https://github.com/1Panel-dev/1Panel) ### Official website: https://www.1panel.cn/ ### Time: 2025 07 26 ### Version: 1panel V2.0.5 ### Vulnerability Summary - First, we introduce the concepts of 1panel v2 Core and Agent. After the new version is released, 1panel adds the node management function, which allows you to control other hosts by adding nodes. - The HTTPS protocol used for communication between the Core and Agent sides did not fully verify the authenticity of the certificate during certificate verification, resulting in unauthorized interfaces. The presence of a large number of command execution or high-privilege interfaces in the 1panel led to RCE.  ### Code audit process 1. First we go to the Agent HTTP routing fileagent/init/router/router.go  2. It was foun...

A new report from Google's GTIG reveals how UNC3944 (0ktapus) uses social engineering to compromise Active Directory, then exploits VMware vSphere for data theft and direct ransomware deployment. Understand their tactics and learn vital mitigation steps.

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-rrjw-j4m2-mf34. This link is maintained to preserve external references. ### Original Description The gix-transport crate before 0.36.1 for Rust allows command execution via the "gix clone 'ssh://-oProxyCommand=open$IFS" substring. NOTE: this was discovered before CVE-2024-32884, a similar vulnerability (involving a username field) that is more difficult to exploit.

Cisco Talos Incident Response (Talos IR) recently observed attacks by Chaos, a relatively new ransomware-as-a-service (RaaS) group conducting big-game hunting and double extortion attacks.

Hewlett-Packard Enterprise (HPE) has released security updates to address a critical security flaw affecting Instant On Access Points that could allow an attacker to bypass authentication and gain administrative access to susceptible systems. The vulnerability, tracked as CVE-2025-37103, carries a CVSS score of 9.8 out of a maximum of 10.0. "Hard-coded login credentials were found in HPE
