Security Vulnerabilities, CVEs, Published In October 2021 CVSS score >= 7

An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges, aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task.

SuiteCRM before 7.11.19 allows remote code execution via the system settings Log File Name setting. In certain circumstances involving admin account takeover, logger_file_name can refer to an attacker-controlled PHP file under the web root, because only the all-lowercase PHP file extensions were blocked. NOTE: this issue exists because of an incomplete fix for CVE-2020-28328.

GJSON before 1.9.3 allows a ReDoS (regular expression denial of service) attack.

Babel.Locale in Babel before 2.9.1 allows attackers to load arbitrary locale .dat files (containing serialized Python objects) via directory traversal, leading to code execution.

The Proof-of-Stake (PoS) Ethereum consensus protocol through 2021-10-19 allows an adversary to cause a denial of service (long-range consensus chain reorganizations), even when this adversary has little stake and cannot influence network message propagation. This can cause a protocol stall, or an increase in the profits of individual validators.

The Proof-of-Stake (PoS) Ethereum consensus protocol through 2021-10-19 allows an adversary to leverage network delay to cause a denial of service (indefinite stalling of consensus decisions).

The Proof-of-Stake (PoS) Ethereum consensus protocol through 2021-10-19 allows an adversary to cause a denial of service (delayed consensus decisions), and also increase the profits of individual validators, via short-range reorganizations of the underlying consensus chain.

The shell-quote package before 1.7.3 for Node.js allows command injection. An attacker can inject unescaped shell metacharacters through a regex designed to support Windows drive letters. If the output of this package is passed to a real shell as a quoted argument to a command with exec(), an attacker can inject arbitrary commands. This is because the Windows drive letter regex character class is {A-z] instead of the correct {A-Za-z]. Several shell metacharacters exist in the space between capital letter Z and lower case letter a, such as the backtick character.

An issue was discovered in stb stb_image.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location.

The bluemonday sanitizer before 1.0.16 for Go, and before 0.0.8 for Python (in pybluemonday), does not properly enforce policies associated with the SELECT, STYLE, and OPTION elements.

The OWASP Java HTML Sanitizer before 20211018.1 does not properly enforce policies associated with the SELECT, STYLE, and OPTION elements.

The affected product is vulnerable to directory traversal due to mishandling of provided backup folder structure.

The affected product is vulnerable to a unsanitized extract folder for system configuration. A low-privileged user can leverage this logic to overwrite the settings and other key functionality.

The affected product is vulnerable to a missing permission validation on system backup restore, which could lead to account take over and unapproved settings change.

The affected product is vulnerable to a parameter injection via passphrase, which enables the attacker to supply uncontrolled input.

The affected product is vulnerable to a disclosure of peer username and password by allowing all users access to read global variables.

Imagicle Application Suite (for Cisco UC) before 2021.Summer.2 allows SQL injection. A low-privileged user could inject a SQL statement through the "Export to CSV" feature of the Contact Manager web GUI.

An issue was discovered in the Dask distributed package before 2021.10.0 for Python. Single machine Dask clusters started with dask.distributed.LocalCluster or dask.distributed.Client (which defaults to using LocalCluster) would mistakenly configure their respective Dask workers to listen on external interfaces (typically with a randomly selected high port) rather than only on localhost. A Dask cluster created using this method (when running on a machine that has an applicable port exposed) could be used by a sophisticated attacker to achieve remote code execution.

An issue was discovered in GoAhead 4.x and 5.x before 5.1.5. In the file upload filter, user form variables can be passed to CGI scripts without being prefixed with the CGI prefix. This permits tunneling untrusted environment variables into vulnerable CGI scripts.

checkpath in OpenRC before 0.44.7 uses the direct output of strlen() to allocate strings, which does not account for the '\0' byte at the end of the string. This results in memory corruption. CVE-2021-42341 was introduced in git commit 63db2d99e730547339d1bdd28e8437999c380cae, which was introduced as part of OpenRC 0.44.0 development.

The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.

The Easytest contains SQL injection vulnerabilities. After obtaining a user’s privilege, remote attackers can inject SQL commands into the parameters of the elective course management page to obtain all database and administrator permissions.

The Easytest contains SQL injection vulnerabilities. After obtaining user’s privilege, remote attackers can inject SQL commands into the parameters of the learning history page to access all database and obtain administrator permissions.

The “Teacher Edit” function of ShinHer StudyOnline System does not perform authority control. After logging in with user’s privilege, remote attackers can access and edit other users’ credential and personal information by crafting URL parameters.

Froxlor through 0.10.29.1 allows SQL injection in Database/Manager/DbManagerMySQL.php via a custom DB name.
