CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2022-23613 – Privilege escalation on xrdp
https://notcve.org/view.php?id=CVE-2022-23613
xrdp is an open source remote desktop protocol (RDP) server. In affected versions an integer underflow leading to a heap overflow in the sesman server allows any unauthenticated attacker which is able to locally access a sesman server to execute code as root. This vulnerability has been patched in version 0.9.18.1 and above. Users are advised to upgrade. There are no known workarounds. xrdp es un servidor de protocolo de escritorio remoto (RDP) de código abierto. • https://github.com/neutrinolabs/xrdp/commit/4def30ab8ea445cdc06832a44c3ec40a506a0ffa https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-8h98-h426-xf32 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K5ONRGARKHGFU2CIEQ7E6M6VJZEM5XWW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U3XGFJNQMNXHBD3J7CBM4YURYEDXROWZ • CWE-191: Integer Underflow (Wrap or Wraparound) •

CVSS: 9.8EPSS: 1%CPEs: 5EXPL: 2CVE-2022-23614 – Code injection in Twig
https://notcve.org/view.php?id=CVE-2022-23614
Twig is an open source template language for PHP. When in a sandbox mode, the `arrow` parameter of the `sort` filter must be a closure to avoid attackers being able to run arbitrary PHP functions. In affected versions this constraint was not properly enforced and could lead to code injection of arbitrary PHP code. Patched versions now disallow calling non Closure in the `sort` filter as is the case for some other filters. Users are advised to upgrade. • https://github.com/davwwwx/CVE-2022-23614 https://github.com/4rtamis/CVE-2022-23614 https://github.com/twigphp/Twig/commit/22b9dc3c03ee66d7e21d9ed2ca76052b134cb9e9 https://github.com/twigphp/Twig/commit/2eb33080558611201b55079d07ac88f207b466d5 https://github.com/twigphp/Twig/security/advisories/GHSA-5mv2-rx3q-4w2v https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I2PVV5DUTRUECTIHMTWRI5Z7DVNYQ2YO https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OTN4 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVSS: 7.4EPSS: 0%CPEs: 35EXPL: 0CVE-2021-20322 – kernel: new DNS Cache Poisoning Attack based on ICMP fragment needed packets replies
https://notcve.org/view.php?id=CVE-2021-20322
A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. Se encontró un fallo en el procesamiento de los errores ICMP recibidos (fragmento ICMP necesario y redireccionamiento ICMP) en la funcionalidad del kernel de Linux que permite la capacidad de escanear rápidamente los puertos UDP abiertos. Este fallo permite a un usuario remoto fuera de la ruta de acceso omitir efectivamente la aleatorización del puerto de origen UDP. • https://bugzilla.redhat.com/show_bug.cgi?id=2014230 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.15-rc6&id=4785305c05b25a242e5314cc821f54ade4c18810 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.15-rc6&id=6457378fe796815c973f631a1904e147d6ee33b1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/ipv4/route.c?h=v5.15-rc6&id=67d6d681e15b578c1725bad8ad079e05d1c48a8e https://git.kernel.org/pub/scm/linux/ke • CWE-330: Use of Insufficiently Random Values •
