Vulnerability from github – Published: 2025-12-11 21:31 – Updated: 2025-12-12 16:42
VLAI
Summary
pgadmin4 has a Meta-Command Filter Command Execution
Details

The PLAIN restore meta-command filter introduced in pgAdmin as part of the fix for CVE-2025-12762 does not detect meta-commands when a SQL file begins with a UTF-8 Byte Order Mark (EF BB BF) or other special byte sequences. The implemented filter uses the function has_meta_commands(), which scans raw bytes using a regular expression. The regex does not treat the bytes as ignorable, so meta-commands such as \\! remain undetected. When pgAdmin invokes psql with --file, psql strips the bytes and executes the command. This can result in remote command execution during a restore operation.

GHSA-G27P-QF6J-C96C

Vulnerability from github – Published: 2026-10-13 20:27 – Updated: 2026-10-19 19:19
VLAI
Summary
Microsoft Security Advisory CVE-2026-102870 - ASP.NET Core Remote Code Execution Vulnerability
Details

Executive summary

Microsoft is releasing this security advisory to provide information about a vulnerability in the Blazor WebAssembly debugger included in Microsoft.AspNetCore.Components.WebAssembly.Server. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.

The Blazor WebAssembly debug proxy evaluates debugger expressions by generating and compiling C# source. Certain values originating in the application being debugged, including ToString() results, descriptions, and class names, are embedded in that generated source without consistent escaping. An attacker-controlled value can escape the generated string literal and execute code on a developer's machine when the developer evaluates an expression during debugging.

Announcement

  "details": "## Executive summary\n\nMicrosoft is releasing this security advisory to provide information about a vulnerability in the Blazor WebAssembly debugger included in `Microsoft.AspNetCore.Components.WebAssembly.Server`. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.\n\nThe Blazor WebAssembly debug proxy evaluates debugger expressions by generating and compiling C# source. Certain values originating in the application being debugged, including `ToString()` results, descriptions, and class names, are embedded in that generated source without consistent escaping. An attacker-controlled value can escape the generated string literal and execute code on a developer\u0027s machine when the developer evaluates an expression during debugging.\n\n## Announcement\n\nAnnouncement for this issue can be found at https://github.com/dotnet/announcements/issues/445\n\n## CVSS Details\n\n- **Version:** 3.1\n- **Severity:** High\n- **Score:** 8.8\n- **Vector:** `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H`\n- **Weakness:** CWE-94 (Improper Control of Generation of Code (\u0027Code Injection\u0027))\n\n## Affected Platforms\n\n- **Platforms:** Windows, Linux, macOS\n- **Architectures:** All\n\n## \u003ca name=\"affected-packages\"\u003e\u003c/a\u003eAffected Packages\n\nThe vulnerability affects Microsoft .NET projects that use an affected package version listed below.\n\nPackage name | Affected version | Patched version\n------------ | ---------------- | ---------------\n[Microsoft.AspNetCore.Components.WebAssembly.Server](https://www.nuget.org/packages/Microsoft.AspNetCore.Components.WebAssembly.Server) | \u003e= 10.0.0, \u003c= 10.0.12 | 10.0.13\n[Microsoft.AspNetCore.Components.WebAssembly.Server](https://www.nuget.org/packages/Microsoft.AspNetCore.Components.WebAssembly.Server) | \u003e= 11.0.0-preview.1, \u003c= 11.0.0-rc.1 | 11.0.0-rc.2.26478.115\n\n## Advisory FAQ\n\n### \u003ca name=\"how-affected\"\u003e\u003c/a\u003eHow do I know if I am affected?\n\nYou are affected if you use a vulnerable version of `Microsoft.AspNetCore.Components.WebAssembly.Server` to debug a Blazor WebAssembly application and evaluate an expression involving attacker-controlled application data.\n\n### \u003ca name=\"how-fix\"\u003e\u003c/a\u003eHow do I fix the issue?\n\n1.

Mitigation
Architecture and Design

Strategy: Refactoring

Refactor your program so that you do not have to dynamically generate code.

Mitigation
Architecture and Design
  • Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
  • Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • To reduce the likelihood of code injection, use stringent allowlists that limit which constructs are allowed. If you are dynamically constructing code that invokes a function, then verifying that the input is alphanumeric might be insufficient. An attacker might still be able to reference a dangerous function that you did not intend to allow, such as system(), exec(), or exit().
Mitigation
Testing

Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.

Mitigation MIT-32
Operation

Strategy: Compilation or Build Hardening

Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).

Strategy: Environment Hardening

Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).

Mitigation
Implementation

For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].

CAPEC-242: Code Injection

An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.

CAPEC-77: Manipulating User-Controlled Variables

This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
