Take a long lunch, and you may miss a critical exploit. But sometimes, time appears to stand still. We just passed 1.6 Billion seconds in the Unix Epoch. Back when the Unix timestamp still had 9 digits, in the late 90s also known as "pre Y2K", one of the servers you may have used for backups was Amanda (Advanced Maryland Automatic Network Disk Archiver).

The client-side sometimes restricts file types, but the server-side does not allowing attackers with direct server access to upload files of any type including malicious files designed to compromise clients that view the data. OnBase also appears to lack the proper mechanisms to verify that files are of the type claimed and instead relies on file extensions, allowing attackers to upload malicious files whose extensions do not match the actual file type. This allows a second vector for malicious file upload and attacking clients. --------------------------------------------- https://cxsecurity.com/issue/WLB-2020090071 ∗∗∗ WordPress Plugin Flaw Allows Attackers to Forge Emails ∗∗∗ --------------------------------------------- The high-severity flaw in the Email Subscribers & Newsletters plugin by Icegram affects more than 100,000 WordPress websites. --------------------------------------------- https://threatpost.com/wordpress-plugin-flaw/159172/ ∗∗∗ Sicherheitsupdates: Root-Lücke bedroht Firewalls von Palo Alto ∗∗∗ --------------------------------------------- Eine kritische Lücke im Betriebssystem PAN-OS gefährdet Firewalls aus dem Hause Palo Alto. --------------------------------------------- https://heise.de/-4892796 ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by CentOS (thunderbird), Debian (libproxy, qemu, and wordpress), Fedora (ansible, chromium, community-mysql, dotnet-build-reference-packages, dotnet3.1, drupal7, grub2, java-1.8.0-openjdk-aarch32, kernel, kernel-headers, kernel-tools, mingw-gnutls, php-symfony4, python-django, and selinux-policy), Gentoo (DBI, file-roller, gnome-shell, gst-rtsp-server, nextcloud-client, php, proftpd, qtgui, and zeromq), openSUSE (gimp, libjpeg-turbo, openldap2, [...] --------------------------------------------- https://lwn.net/Articles/831524/ ∗∗∗ Vulnerabilities Expose Thousands of MobileIron Servers to Remote Attacks ∗∗∗ --------------------------------------------- Researchers have disclosed the details of several potentially serious vulnerabilities affecting MobileIron’s mobile device management (MDM) solutions, including a flaw that can be exploited by an unauthenticated attacker for remote code execution on affected servers. --------------------------------------------- https://www.securityweek.com/vulnerabilities-expose-thousands-mobileiron-se… ∗∗∗ Multiple vulnerabilities in Buffalo AirStation WHR-G54S ∗∗∗ --------------------------------------------- https://jvn.jp/en/jp/JVN09166495/ ∗∗∗ Security Bulletin: IBM Cloud Pak System is affected by a vulnerability in VMware component ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-cloud-pak-system-is-a… ∗∗∗ Security Bulletin: A vulnerability in Apache AvtiveMQ affects IBM Operations Analytics Predictive Insights (CVE-2020-1941) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-apache… ∗∗∗ Security Bulletin: Vulnerability in libcurl affects the OS image for RedHat Enterprise Linux for IBM Cloud Pak System (CVE-2019-5436) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-libcurl-… ∗∗∗ Security Bulletin: Vulnerability in OpenSSL library affects OS Pattern Kit used in IBM Cloud Pak System ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-openssl-… ∗∗∗ Security Bulletin: IBM Kenexa LMS On Premise -IBM SDK, Java Technology Edition Quarterly CPU -Jul 2020 – Includes Oracle Jul 2020 CPU plus one additional vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-kenexa-lms-on-premise… ∗∗∗ Security Bulletin: IBM Kenexa LCMS Premier On Premise – [All] jQuery (Publicly disclosed vulnerability) CVEID: 180875 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-kenexa-lcms-premier-o… ∗∗∗ Security Bulletin: Vulnerability in side channel in Intel CPUs affect IBM Cloud Pak System (CVE-2019-11135) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-side-cha… ∗∗∗ Security Bulletin: IBM Kenexa LCMS Premier On Premise – [All] jQuery (Publicly disclosed vulnerability) CVE-2020-11023, CVE-2020-11022 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-kenexa-lcms-premier-o… ∗∗∗ Security Bulletin: Multiple vulnerabilities in IBM Java SDK addressed in IBM Cloud Pak System (April 2020 updates) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily
