Advisory FAQ

How do I know if I am affected?

If using a package listed in affected packages, you're exposed to the vulnerability.

How do I fix the issue?

  1. To fix the issue please install the latest version of .NET. If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET SDKs.
  2. If your application references the vulnerable nuget package, update the package reference to the patched version. You can list the versions you have installed by running the dotnet --info command.

Once you have installed the updated runtime or SDK, restart your apps for the update to take effect.

Additionally, if you've deployed self-contained applications targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.

Vulnerability from github – Published: 2025-04-09 21:31 – Updated: 2025-04-09 21:31
VLAI
Details

An Improper Encoding or Escaping of Output vulnerability in the Sampling Route Record Daemon (SRRD) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).

When a device configured for flow-monitoring receives a specific BGP update message, it is correctly processed internally by the routing protocol daemon (rpd), but when it's sent to SRRD it's encoded incorrectly which leads to a crash and momentary interruption of jflow processing until it automatically restarts. This issue does not affect traffic forwarding itself. This issue affects Junos OS: 

  • All versions before 21.2R3-S9,
  • 21.4 versions before 21.4R3-S10,
  • 22.2 versions before 22.2R3-S6,
  • 22.4 versions before 22.4R3,
  • 23.2 versions before 23.2R1-S2, 23.2R2.

This issue does not affected Junos OS Evolved.

Vulnerability from github – Published: 2025-03-26 20:34 – Updated: 2025-03-26 20:34
VLAI
Summary
Django TomSelect incomplete escaping of dangerous characters in widget attributes
Details

Summary

User supplied values passed through to certain attributes in form widgets are not fully escaped for potentially dangerous tokens, and in some cases are rendered in browser as valid html tags.

Details

Attributes passed to the widget (such as label_field) containing <, >, and similar tokens are not fully escaped. This results in some raw values reaching the widget, and rendering in part or fully.

For example, a label of: "Test User <script>I can pass this to the label_field and it gets rendered</script>" is rendered in the choices's label visually as "Test User " with the trailing space, and what appears as an un-executed script tag following it (which is visible when viewing source).

The actual output rendered in the browser for this example is: <div role="option" data-value="63f205b6" class="item" data-ts-item="">Test User <script>I can pass this to the label_field and it gets rendered</script></div>

The script tags appears to be valid in Chrome dev tools, but doesn't appear execute code.

Impact

Although the risk may be mediated since the content within the rendered <script></script> tags does not seem to actually/immediately run, potential may exist for other ways of increasing the risk (e.g.: code injection). In addition, the widget does not display correctly for valid strings containing < or >. Valid use-cases for printing these characters include widget label fields displaying email addresses (e.g.: "User Jane <user.jane@example.com>"

Because of the relatively small number of users at this moment, our plan to yank affected releases on PyPI and GitHub, and because raw text is rendered but does not seem to be executable, I am marking the Severity Low.

Update to version 5.3.3. The only difference from 5.3.2 is the code and documentation changes to resolve this vulnerability, so the update process should not be problematic.

In addition, the widget does not display correctly for valid strings containing `\u003c` or `\u003e`. Valid use-cases for printing these characters include widget label fields displaying email addresses (e.g.: `\"User Jane \u003cuser.jane@example.com\u003e\"`\n\nBecause of the relatively small number of users at this moment, our plan to yank affected releases on PyPI and GitHub, and because raw text is rendered but does not seem to be executable, I am marking the Severity **Low**.\n\nUpdate to version **5.3.3**.

Details

Improper Output Neutralization for Logs (CWE-117) in Kibana can lead to log injection via Log Injection-Tampering-Forging (CAPEC-93). An attacker can supply specially crafted input that is written to log files without proper neutralization. When the log files are subsequently viewed in a terminal that interprets control sequences, the injected content may alter the displayed log data.

Mitigation MIT-4.3
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using the ESAPI Encoding control [REF-45] or a similar tool, library, or framework. These will help the programmer encode outputs in a manner less prone to error.
  • Alternately, use built-in functions, but consider using wrappers in case those functions are discovered to have a vulnerability.
Mitigation MIT-27
Architecture and Design

Strategy: Parameterization

  • If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
  • For example, stored procedures can enforce database query structure and reduce the likelihood of SQL injection.
Mitigation
Architecture and Design Implementation

Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages. Study all expected communication protocols and data representations to determine the required encoding strategies.

Mitigation
Architecture and Design

In some cases, input validation may be an important strategy when output encoding is not a complete solution. For example, you may be providing the same output that will be processed by multiple consumers that use different encodings or representations. In other cases, you may be required to allow user-supplied input to contain control information, such as limited HTML tags that support formatting in a wiki or bulletin board. When this type of requirement must be met, use an extremely strict allowlist to limit which control sequences can be used. Verify that the resulting syntactic structure is what you expect. Use your normal encoding methods for the remainder of the input.

Mitigation
Architecture and Design

Use input validation as a defense-in-depth measure to reduce the likelihood of output encoding errors (see CWE-20).

Mitigation
Requirements

Fully specify which encodings are required by components that will be communicating with each other.

Mitigation
Implementation

When exchanging data between components, ensure that both components are using the same character encoding. Ensure that the proper encoding is applied at each interface. Explicitly set the encoding you are using whenever the protocol allows you to do so.

CAPEC-104: Cross Zone Scripting

An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security.

CAPEC-73: User-Controlled Filename

An attack of this type involves an adversary inserting malicious characters (such as a XSS redirection) into a filename, directly or indirectly that is then used by the target software to generate HTML text or other potentially executable content. Many websites rely on user-generated content and dynamically build resources like files, filenames, and URL links directly from user supplied data. In this attack pattern, the attacker uploads code that can execute in the client browser and/or redirect the client browser to a site that the attacker owns. All XSS attack payload variants can be used to pass and exploit these vulnerabilities.

CAPEC-81: Web Server Logs Tampering

Web Logs Tampering attacks involve an attacker injecting, deleting or otherwise tampering with the contents of web logs typically for the purposes of masking other malicious behavior. Additionally, writing malicious data to log files may target jobs, filters, reports, and other agents that process the logs in an asynchronous attack pattern. This pattern of attack is similar to "Log Injection-Tampering-Forging" except that in this case, the attack is targeting the logs of the web server and not the application.

CAPEC-85: AJAX Footprinting

This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. A common first step for an attacker is to footprint the target environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on. The knowledge gained through Ajax fingerprinting can be used to support other attacks, such as XSS.
