3CX before 18 Hotfix 1 build 18.0.3.461 on Windows allows unauthenticated remote attackers to read %WINDIR%\system32 files via /Electron/download directory traversal in conjunction with a path component that has a drive letter and uses backslash characters. NOTE: this issue exists because of an incomplete fix for CVE-2022-28005.
In AVideo, a normal user can make a Meeting Schedule where the user can invite another user in that Meeting, but I found out that it did not properly sanitize the malicious characters when creating a Meeting Room. This leads the attacker to put malicious scripts. Impact: Since any USER including the ADMIN can see the meeting room that was created by the attacker this can lead to cookie hijacking and takeover of any accounts without user interaction. Step to Reproduce: 1. As normal USER go to Meet -> Schedule https://demo.avideo.com/plugin/Meet/ 2. In "Meet topic" field put XSS payload Example: "><img src=x onerror=alert('Pawned+by+Gonz')> 3. Then click Save 4. Now as ADMIN go to Meet -> Schedule -> Upcoming https://demo.avideo.com/plugin/Meet/ 5. Then the XSS payload that normal USER created will be executed Video POC: https://youtu.be/Nke0Bmv5F-o
This Metasploit module exploits a remote unauthenticated deserialization of untrusted data vulnerability in Adobe ColdFusion 2021 Update 5 and earlier as well as ColdFusion 2018 Update 15 and earlier, in order to gain remote code execution.
Ubuntu Security Notice 6052-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for thisCVE, kernel support for the TCINDEX classifier has been removed.
Ubuntu Security Notice 6051-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for thisCVE, kernel support for the TCINDEX classifier has been removed. It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
Ubuntu Security Notice 6049-1 - It was discovered that Netty's Zlib decoders did not limit memory allocations. A remote attacker could possibly use this issue to cause Netty to exhaust memory via malicious input, leading to a denial of service. This issue only affected Ubuntu 16.04 ESM and Ubuntu 20.04 ESM. It was discovered that Netty created temporary files with excessive permissions. A local attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 ESM, and Ubuntu 20.04 ESM.
Apache StreamPark versions 1.0.0 to 2.0.0 have an LDAP injection vulnerability. LDAP Injection is an attack used to exploit web based applications that construct LDAP statements based on user input. When an application fails to properly sanitize user input, it's possible to modify LDAP statements through techniques similar to SQL Injection. LDAP injection attacks could result in the granting of permissions to unauthorized queries, and content modification inside the LDAP tree. This risk may only occur when the user logs in with ldap, and the user name and password login will not be affected, Users of the affected versions should upgrade to Apache StreamPark 2.0.0 or later.

A heap out-of-bounds read/write vulnerability in the Linux Kernel traffic control (QoS) subsystem can be exploited to achieve local privilege escalation. The qfq_change_class function does not properly limit the lmax variable which can lead to out-of-bounds read/write. If the TCA_QFQ_LMAX value is not offered through nlattr, lmax is determined by the MTU value of the network device. The MTU of the loopback device can be set up to 2^31-1 and as a result, it is possible to have an lmax value that exceeds QFQ_MIN_LMAX. We recommend upgrading past commit 3037933448f60f9acb705997eae62013ecb81e0d.
