IBM i 7.6, 7.5, 7.4, and 7.3, IBM WebSphere Application Server, and IBM WebSphere Application Server Liberty are vulnerable to denial of service in the WebSphere WebServer Plug-in component when an attacker can pass crafted requests to the web server.

IBM WebSphere Application Server and IBM WebSphere Application Server Liberty are vulnerable to remote code execution and denial of service in the WebSphere Web Server Plug-in component. This vulnerability can be exploited when an attacker impersonates the application server and sends crafted responses to the plug-in.

IBM Web Server Plug-ins for WebSphere Application Server and WebSphere Liberty 8.5, 9.0 IBM WebSphere Application Server and WebSphere Application Server Liberty are vulnerable to HTTP request smuggling in the Web Server Plug-ins through a specially crafted request.

IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.4 IBM WebSphere Application Server Liberty is vulnerable to identity spoofing under limited conditions when an application is deployed without authentication and authorization configured.

Impact

A vulnerability in Multer versions >= 1.4.4-lts.1, < 2.0.2 allows an attacker to trigger a Denial of Service (DoS) by sending a malformed request. This request causes an unhandled exception, leading to a crash of the process.

Patches

Users should upgrade to 2.0.2

Workarounds

None

Impact v3.0.8, v2.1.2, v1.16.4 and below

Patches Has been patched in 3.0.9, 2.1.3, and 1.16.5

Workarounds You can use the ignore option to ignore non files/directories.

js ignore (, header) { // pass files & directories, ignore e.g. symlinks return header.type !== 'file' && header.type !== 'directory' }

An Improper Link Resolution Before File Access ("Link Following") and Improper Limitation of a Pathname to a Restricted Directory ("Path Traversal"). This vulnerability occurs when extracting a maliciously crafted tar file, which can result in unauthorized file writes or overwrites outside the intended extraction directory. The issue is associated with index.js in the tar-fs package.

Sensitive headers incorrectly sent after cross-domain redirect in net/http

get-func-name is a module to retrieve a function's name securely and consistently both in NodeJS and the browser. Versions prior to 2.0.1 are subject to a regular expression denial of service (redos) vulnerability which may lead to a denial of service when parsing malicious input. This vulnerability can be exploited when there is an imbalance in parentheses, which results in excessive backtracking and subsequently increases the CPU load and processing time significantly. This vulnerability can be triggered using the following input: '\t'.repeat(54773) + '\t/function/i'. This issue has been addressed in commit f934b228b which has been included in releases from 2.0.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

A flaw was found in the Node.js word-wrap module, where it is vulnerable to a denial of service caused by a Regular expression denial of service (ReDoS) issue in the result variable. By sending a specially crafted regex input, a remote attacker can cause a denial of service.

Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the Cookie.parse function, which uses an insecure regular expression.

A flaw was found in the json5 package. The affected version of the json5 package could allow an attacker to set arbitrary and unexpected keys on the object returned from JSON5.parse.

hoek before 8.5.1 and 9.x before 9.0.3 allows prototype poisoning in the clone function.

A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.

A flaw was found in the ShellJS library when the scripts used the exec function. Local users on the filesystem could take advantage of this as they can read the stdout of the ShellJS process. This issue discloses sensitive information, leading to privilege escalation. This flaw allows an attacker to craft stdout files, which leads to crashing the ShellJS scripts running with privileges.

GNU Multiple Precision Arithmetic Library (GMP) through 6.2.1 has an mpz/inpraw.c integer overflow and resultant buffer overflow via crafted input, leading to a segmentation fault on 32-bit platforms.

Buffer overflow vulnerability in function poolinstallablewhatprovides in src/repo.h in libsolv before 0.7.17 allows attackers to cause a Denial of Service.

Buffer overflow vulnerability in function poolinstallable in src/repo.h in libsolv before 0.7.17 allows attackers to cause a Denial of Service.

A flaw was found in libsolv. A buffer overflow vulnerability in the prunetorecommend function allows attackers to cause a denial of service. The highest threat from this vulnerability is to system availability.

A flaw was found in libsolv. A buffer overflow vulnerability in the pooldisabledsolvable function allows attackers to cause a denial of service. The highest threat from this vulnerability is to system availability.

All versions of package trim are vulnerable to Regular Expression Denial of Service (ReDoS) via trim().

pathval before version 1.1.1 is vulnerable to prototype pollution.

Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).

Proof of Concept js var minimatch = require(“minimatch”);

// utility function for generating long strings var genstr = function (len, chr) { var result = “”; for (i=0; i<=len; i++) { result = result + chr; } return result; }

var exploit = “[!” + genstr(1000000, “\\”) + “A”;

// minimatch exploit. console.log(“starting minimatch”); minimatch(“foo”, exploit); console.log(“finishing minimatch”);

Recommendation

Update to version 3.0.2 or later.
