The Anveo Server is also vulnerable against user enumeration because of different error messages for existing vs. non-existing users. The vendor was unresponsive and did not reply to our communication attempts and even deleted our comment to request a contact on LinkedIn, see the timeline section further below. --------------------------------------------- https://sec-consult.com/vulnerability-lab/advisory/missing-certificate-vali… ∗∗∗ Security updates for Tuesday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (cryptojs, fastdds, mediawiki, and minizip), Fedora (chromium, kubernetes, and thunderbird), Mageia (lilypond, mariadb, and packages), Red Hat (firefox, linux-firmware, and thunderbird), SUSE (compat-openssl098, gstreamer-plugins-bad, squashfs, squid, thunderbird, vim, and xerces-c), and Ubuntu (libtommath, linux-intel-iotg, linux-intel-iotg-5.15, linux-oracle, perl, and python3.8, python3.10, python3.11). --------------------------------------------- https://lwn.net/Articles/953099/ ∗∗∗ Critical Vulnerability Found in Ray AI Framework ∗∗∗ --------------------------------------------- Tracked as CVE-2023-48023, the bug exists because Ray does not properly enforce authentication on at least two of its components, namely the dashboard and client.

More often than not, these tokens are leaked somewhere. When these tokens are exfiltrated during a Red Team exercise, it can be a pain to properly utilize them. Now EvilSlackbot is here to automate and streamline that process. You can use EvilSlackbot to send spoofed Slack messages, phishing links, files, and search for secrets leaked in slack. [..] In addition to red teaming, EvilSlackbot has also been developed with Slack phishing simulations in mind. --------------------------------------------- https://github.com/Drew-Sec/EvilSlackbot ∗∗∗ Scans for ownCloud Vulnerability (CVE-2023-49103), (Mon, Nov 27th) ∗∗∗ --------------------------------------------- Last week, ownCloud released an advisory disclosing a new vulnerability, CVE-2023-49103 [1]. The vulnerability will allow attackers to gain access to admin passwords. To exploit the vulnerability, the attacker will use the "graphapi" app to access the output of "phpinfo". If the ownCloud install runs in a container, it will allow access to admin passwords, mail server credentials, and license keys. --------------------------------------------- https://isc.sans.edu/diary/rss/30432 ∗∗∗ WordPress Vulnerability & Patch Roundup November 2023 ∗∗∗ --------------------------------------------- Vulnerability reports and responsible disclosures are essential for website security awareness and education. Automated attacks targeting known software vulnerabilities are one of the leading causes of website compromises. To help educate website owners on emerging threats to their environments, we’ve compiled a list of important security updates and vulnerability patches for the WordPress ecosystem this past month. --------------------------------------------- https://blog.sucuri.net/2023/11/wordpress-vulnerability-patch-roundup-novem… ∗∗∗ Experts Uncover Passive Method to Extract Private RSA Keys from SSH Connections ∗∗∗ --------------------------------------------- A new study has demonstrated that its possible for passive network attackers to obtain private RSA host keys from a vulnerable SSH server by observing when naturally occurring computational faults that occur while the connection is being established. [..] The researchers described the method as a lattice-based key recovery fault attack, which allowed them to retrieve the private keys corresponding to 189 unique RSA public keys that were subsequently traced to devices from four manufacturers: Cisco, Hillstone Networks, Mocana, and Zyxel. --------------------------------------------- https://thehackernews.com/2023/11/experts-uncover-passive-method-to.html ∗∗∗ Eine Milliarde unsichere Webseiten … Vergessen Sie die Duschmatte nicht! ∗∗∗ --------------------------------------------- In der Werbung aufgebauschte Risiken dienen eher dem Verkauf von Sicherheitsprodukten als der Sicherheit selbst.

Wir raten aber von einer Bestellung ab, da Sie nur mit einem Paysafecard- oder Amazon-Code bezahlen können und Ihre Bestellung nicht erhalten. --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-fake-shops-fuer-skins/ ∗∗∗ Warnung vor betrügerischen Mails im Namen von Finanz Online ∗∗∗ --------------------------------------------- Die täuschend echt wirkenden E-Mails verlinken auf eine gefälschte Website, auf der die Opfer wiederum ihre Bankdaten eingeben sollen --------------------------------------------- https://www.derstandard.at/story/3000000197015/warnung-betrugs-mails-finanz… ∗∗∗ LKA-Warnung vor gefälschten Temu-Benachrichtigungen ∗∗∗ --------------------------------------------- Das Landeskriminalamt Niedersachsen hat die Tage eine Warnung herausgegeben, die Kunden des chinesischen Billig-Versandhändlers Temu betrifft.
