Security Vulnerabilities, CVEs, (Memory corruption)
CVE-2024-25004
Public exploit
KiTTY versions 0.76.1.13 and before is vulnerable to a stack-based buffer overflow via the username, occurs due to insufficient bounds checking and input sanitization (at line 2600). This allows an attacker to overwrite adjacent memory, which leads to arbitrary code execution.

CVE-2021-31802
Public exploit
NETGEAR R7000 1.0.11.116 devices have a heap-based Buffer Overflow that is exploitable from the local network without authentication. The vulnerability exists within the handling of an HTTP request. An attacker can leverage this to execute code as root. The problem is that a user-provided length value is trusted during a backup.cgi file upload. The attacker must add a \n before the Content-Length header.

CVE-2021-4034
Known exploited
Public exploit
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.

CVE-2021-3490
Public exploit
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e ("bpf: Fix alu32 const subreg bound tracking on bitwise operations") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. The AND/OR issues were introduced by commit 3f50f132d840 ("bpf: Verifier, do explicit ALU32 bounds tracking") (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 ("bpf:Fix a verifier failure with xor") ( 5.10-rc1).

CVE-2020-14871
Known exploited
Public exploit
Vulnerability in the Oracle Solaris product of Oracle Systems (component: Pluggable authentication module). Supported versions that are affected are 10 and 11. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Solaris. While the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Oracle Solaris. Note: This CVE is not exploitable for Solaris 11.1 and later releases, and ZFSSA 8.7 and later releases, thus the CVSS Base Score is 0.0. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
