Vulnerability from github – Published: 2020-06-10 20:02 – Updated: 2021-08-30 13:21
VLAI
Summary
Insecure Deserialization in Apache XML-RPC
Details

An untrusted deserialization was found in the org.apache.xmlrpc.parser.XmlRpcResponseParser:addResult method of Apache XML-RPC (aka ws-xmlrpc) library. A malicious XML-RPC server could target a XML-RPC client causing it to execute arbitrary code.

Apache XML-RPC is no longer maintained and this issue will not be fixed.

Vulnerability from github – Published: 2022-04-07 00:00 – Updated: 2022-04-15 00:01
VLAI
Details

A vulnerability in the login authorization components of Cisco Webex Meetings could allow an authenticated, remote attacker to inject arbitrary Java code. This vulnerability is due to improper deserialization of Java code within login requests. An attacker could exploit this vulnerability by sending malicious login requests to the Cisco Webex Meetings service. A successful exploit could allow the attacker to inject arbitrary Java code and take arbitrary actions within the Cisco Webex Meetings application.

GHSA-6W4W-5W54-RJVR

Vulnerability from github – Published: 2025-08-26 18:37 – Updated: 2026-07-18 17:26
VLAI
Summary
Picklescan has a missing detection when calling built-in python idlelib.autocomplete.AutoComplete.get_entity
Details

Summary

Using idlelib.autocomplete.AutoComplete.get_entity, which is a built-in python library function to execute remote pickle file.

Details

The attack payload executes in the following steps:

First, the attacker craft the payload by calling to idlelib.autocomplete.AutoComplete.get_entity function in reduce method Then when the victim after checking whether the pickle file is safe by using Picklescan library and this library doesn't dectect any dangerous functions, decide to pickle.load() this malicious pickle file, thus lead to remote code execution.

PoC

class EvilIdlelibAutocompleteGetEntity:
    def __reduce__(self):
        from idlelib.autocomplete import AutoComplete
        return AutoComplete().get_entity, ("__import__('os').system('whoami')",)

Impact

Who is impacted? Any organization or individual relying on picklescan to detect malicious pickle files inside PyTorch models. What is the impact? Attackers can embed malicious code in pickle file that remains undetected but executes when the pickle file is loaded. Supply Chain Attack: Attackers can distribute infected pickle files across ML models, APIs, or saved Python objects.

Vulnerability from github – Published: 2021-08-25 14:46 – Updated: 2022-02-08 20:43
VLAI
Summary
XStream is vulnerable to an Arbitrary Code Execution attack
Details

Impact

The vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches

XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

Workarounds

See workarounds for the different versions covering all CVEs.

References

See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2021-39154.

Credits

ka1n4t found and reported the issue to XStream and provided the required information to reproduce it.

Vulnerability from github – Published: 2024-12-07 12:30 – Updated: 2024-12-07 12:30
VLAI
Details

The Gallery plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.3 via deserialization of untrusted input from wd_gallery_$id parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Vulnerability from github – Published: 2021-08-25 14:48 – Updated: 2022-02-08 20:59
VLAI
Summary
XStream can cause a Denial of Service
Details

Impact

The vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches

XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

Workarounds

See workarounds for the different versions covering all CVEs.

References

See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2021-39140.

Credits

The vulnerability was discovered and reported by Lai Han of nsfocus security team.

Vulnerability from github – Published: 2025-11-05 03:30 – Updated: 2025-11-05 03:30
VLAI
Details

The Everest Forms (Pro) plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.9.7 via deserialization of untrusted input in the mime_content_type() function. This makes it possible for unauthenticated attackers to inject a PHP Object. This vulnerability may be exploited by unauthenticated attackers when a form is present on the site with a non-required signature form field along with an image upload field. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. This vulnerability is only exploitable in PHP versions prior to 8.

Mitigation
Architecture and Design Implementation

If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.

Mitigation
Implementation

When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.

Mitigation
Implementation

Explicitly define a final object() to prevent deserialization.

Mitigation
Architecture and Design Implementation
  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation
Implementation

Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.

Mitigation
Architecture and Design Implementation

Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.

Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-586: Object Injection

An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
