CVSS: 7.8EPSS: 0%CPEs: 56EXPL: 33CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. • https://github.com/dzonerzy/poc-cve-2021-4034 https://github.com/arthepsy/CVE-2021-4034 https://github.com/berdav/CVE-2021-4034 https://www.exploit-db.com/exploits/50689 https://github.com/PwnFunction/CVE-2021-4034 https://github.com/joeammond/CVE-2021-4034 https://github.com/nikaiw/CVE-2021-4034 https://github.com/ryaagard/CVE-2021-4034 https://github.com/Rvn0xsy/CVE-2021-4034 https://github.com/Ayrx/CVE-2021-4034 https://github.com/zhzyker/CVE-2021-4034& • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVSS: 5.9EPSS: 1%CPEs: 9EXPL: 0CVE-2021-36221 – golang: net/http/httputil: panic due to racy read of persistConn after handler panic
https://notcve.org/view.php?id=CVE-2021-36221
Go before 1.15.15 and 1.16.x before 1.16.7 has a race condition that can lead to a net/http/httputil ReverseProxy panic upon an ErrAbortHandler abort. Go versiones anteriores a 1.15.15 y 1.16.x versiones anteriores a 1.16.7, presenta una condición de carrera que puede conllevar un pánico de net/http/httputil ReverseProxy al abortar ErrAbortHandler A race condition flaw was found in Go. The incoming requests body weren't closed after the handler panic and as a consequence this could lead to ReverseProxy crash. The highest threat from this vulnerability is to Availability. • https://cert-portal.siemens.com/productcert/pdf/ssa-222547.pdf https://groups.google.com/forum/#%21forum/golang-announce https://groups.google.com/g/golang-announce/c/JvWG9FUUYT0 https://groups.google.com/g/golang-announce/c/uHACNfXAZqk https://lists.debian.org/debian-lts-announce/2022/01/msg00016.html https://lists.debian.org/debian-lts-announce/2022/01/msg00017.html https://lists.debian.org/debian-lts-announce/2023/04/msg00021.html https://lists.fedoraproject.org/archives/list/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
