Summary
skilleton has improper input handling in repository/path processing
Details

Summary

skilleton versions prior to 0.3.1 include security-related weaknesses in repository normalization and path handling logic.
Version 0.3.1 contains fixes and additional test coverage for these issues.

Affected Versions

<0.3.1

Patched Versions

>=0.3.1

Impact

In affected versions, crafted input could trigger unsafe or inefficient behavior in repository/path processing code paths.
0.3.1 mitigates this by: - replacing vulnerable parsing behavior with deterministic logic, - validating subpaths earlier before allocating git worktree resources, - adding stricter and broader regression tests around these flows.

Severity

Low to Moderate (project-maintainer assessed)

Mitigation

Upgrade to 0.3.1 or later.

Workarounds

No complete workaround is recommended other than upgrading.

Credits

Detected through automated code scanning and remediated by project maintainers.

Vulnerability from github – Published: 2022-05-24 16:57 – Updated: 2023-04-20 15:30
VLAI
Details

A vulnerability in the configuration of the Pluggable Authentication Module (PAM) used in Cisco Firepower Threat Defense (FTD) Software, Cisco Firepower Management Center (FMC) Software, and Cisco FXOS Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper resource management in the context of user session management. An attacker could exploit this vulnerability by connecting to an affected system and performing many simultaneous successful Secure Shell (SSH) logins. A successful exploit could allow the attacker to exhaust system resources and cause the device to reload, resulting in a DoS condition. To exploit this vulnerability, the attacker needs valid user credentials on the system.

Vulnerability from github – Published: 2021-06-23 17:26 – Updated: 2026-01-23 22:35
VLAI
Summary
Websocket requests did not call AuthenticateMethod
Details

Impact

Depending on implementation, a denial-of-service or privilege escalation vulnerability may occur in software that uses the github.com/ecnepsnai/web package with Web Sockets that have an AuthenticateMethod.

The AuthenticateMethod is not called, and UserData will be nil in request methods. Attempts to read the UserData may result in a panic.

This issue only affects web sockets where an AuthenticateMethod is supplied to the handle options. Users who do not use web sockets, or users who do not require authentication are not at risk.

Example

In the example below, one would expect that the AuthenticateMethod function would be called for each request to /example

handleOptions := web.HandleOptions{
    AuthenticateMethod: func(request *http.Request) interface{} {
        // Assume there is logic here to check for an active sessions, look at cookies or headers, etc...
        var session Session{} // Example

        return session
    },
}

server.Socket("/example", handle, handleOptions)

However, the method is not called, and therefor the UserData parameter of the request object in the handle will be nil, when it would have been expected to be the session object we returned.

Patches

Release v1.5.2 fixes this vulnerability. The authenticate method is now called for websocket requests.

All users of the web package should update to v1.5.2 or later.

Workarounds

You may work around this issue by making the authenticate method a named function, then calling that function at the start of the handle method for the websocket. Reject connections when the return value of the method is nil.

GHSA-5GP7-J4R7-G66F

Vulnerability from github – Published: 2023-12-10 18:30 – Updated: 2025-11-04 21:30
VLAI
Details

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.

Vulnerability from github – Published: 2022-05-24 16:50 – Updated: 2022-05-24 16:50
VLAI
Details

A vulnerability in the pfe-chassisd Chassis Manager (CMLC) daemon of Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the EX4300 when specific valid broadcast packets create a broadcast storm condition when received on the me0 interface of the EX4300 Series device. A reboot of the device is required to restore service. Continued receipt of these valid broadcast packets will create a sustained Denial of Service (DoS) against the device. Affected releases are Juniper Networks Junos OS: 16.1 versions above and including 16.1R1 prior to 16.1R7-S5; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S2; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2.

Mitigation
Architecture and Design

Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.

Mitigation
Architecture and Design
  • Mitigation of resource exhaustion attacks requires that the target system either:
  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
  • The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
  • recognizes the attack and denies that user further access for a given amount of time, or
  • uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design

Ensure that protocols have specific limits of scale placed on them.

Mitigation
Implementation

Ensure that all failures in resource allocation place the system into a safe posture.

CAPEC-147: XML Ping of the Death

An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.

CAPEC-227: Sustained Client Engagement

An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.

CAPEC-492: Regular Expression Exponential Blowup

An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
