April 14, 2024 - CVE-2023-24534 HTTP and MIME Header Parsing Can Allocate Large Amounts of Memory - 7.5 CVSS​

HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers.

An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. With the fix, header parsing now correctly allocates only the memory required to hold parsed headers.

Impact​

Low.

Patches​

Palette and VerteX version 4.3.0 include the security patch for the vulnerability.

Workarounds​

Not applicable.

April 14, 2024 - CVE-2023-24536 MIME/Multipart Form Parsing Can Consume Large Amounts of CPU and Memory - 7.5 CVSS​

Multipart form parsing can consume large amounts of CPU and memory when processing form inputs containing large numbers of parts. This can be caused by several reasons:

  • mime/multipart.Reader.ReadForm limits the total memory a parsed multipart form can consume. ReadForm can undercount the amount of memory consumed, leading it to accept larger inputs than intended.
  • Limiting total memory does not account for increased pressure on the garbage collector from large numbers of small allocations in forms with many parts.
  • ReadForm can allocate a large number of short-lived buffers, further increasing pressure on the garbage collector.

The combination of these factors can allow an attacker to cause a program that parses multipart forms to consume large amounts of CPU and memory, potentially resulting in a denial of service. This affects programs that use mime/multipart.Reader.ReadForm and form parsing in the net/http package with the request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue. With the fix, ReadForm now better estimates the memory consumption of parsed forms and performs fewer short-lived allocations. In addition, the fixed mime/multipart.Reader imposes the following limits on the size of parsed forms:

  • Forms parsed with ReadForm may contain no more than 1000 parts. This limit can be adjusted with the environment variable GODEBUG=multipartmaxparts=.
  • Form parts parsed with NextPart and NextRawPart may contain no more than 10,000 header fields. In addition, forms parsed with ReadForm may contain no more than 10,000 header fields across all parts. This limit may be adjusted with the environment variable GODEBUG=multipartmaxheaders=.

Impact​

Low.

Patches​

January 10, 2024 - CVE-2023-45283 Filepath Package and Special Prefixes - 7.5 CVSS​

The filepath package does not recognize paths with a \??\ prefix as special. On Windows, a path beginning with \??\ is a Root Local Device (RDL) path equivalent to a path beginning with \\?\. Paths with a \??\ prefix may be used to access arbitrary locations on the system. For example, the path \??\c:\x is equivalent to the more common path c:\x.

Before the fix, the Clean function could convert a rooted path such as \a\..\??\b into the RDL path \??\b. Clean will now convert this to .\??\b. Similarly, before the fix, Join(\, ??, b) could convert a seemingly innocent sequence of path elements into the RDL path ??\b. Join will now convert this to \.\??\b.

In the fix version, the function IsAbs now correctly reports paths beginning with \??\ as absolute, and VolumeName correctly reports the \??\ prefix as a volume name.

Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the volume name in Windows paths starting with \?, resulting in filepath.Clean(\?\c:) returning \?\c: rather than \?\c:\ among other effects. The previous expected behavior has been restored in the new version releases.

Impact​

No impact. This only impacts Windows and Palette does not use Windows operating systems for runtime operations.

January 10, 2024 - CVE-2023-39325 Excessive Server Resource Consumption - 7.5 CVSS​

A malicious HTTP/2 client that rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing.

With the fix applied, HTTP/2 servers are now bound by the number of simultaneously executing handler goroutines to the stream concurrency limit MaxConcurrentStreams.

If a client sends a new request when the server is already processing the maximum number of requests, the new request will be queued and wait for a handler to become available. However, if the queue of pending requests grows too large, the server will terminate the connection. This will happen only after the client has reset an existing request that is still being processed by the server.

This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams requests per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package. Refer to the Server.MaxConcurrentStreams setting and the ConfigureServer function for more details.

Impact​

All Palette and VerteX releases prior to version 4.2.0 are impacted. The impact is largely mitigated as Palette and VerteX already have IP address based rate limit.

Patches​

Palette and VerteX version 4.1.0 includes the fix for all the services using the HTTP/2 protocol.

Workarounds​

No workaround available. Impact is largely mitigated by the rate limits on the API requests. Refer to the API Rate Limit documentation for more information.

January 10, 2024 - CVE-2022-4886 Nginx Path Sanitization Bypass - 8.8 CVSS​

The Kubernetes ingress-nginx controller path sanitization feature can be bypassed with the log_format directive.

Impact​

No impact on Palette SaaS, self-hosted Palette, or VerteX deployments. We do not allow end user to create or update ingress objects. Tenant clusters using the Nginx ingress controller pack with versions older than v1.8.0 may be impacted if they expose the ability for end users to create or update ingress objects.

Patches​

No fix is available yet, but there is a remediation available starting with Nginx ingress controller v1.8.0. The Nginx ingress controller pack is available with a newer version v1.9.4. The newer version has enable-annotation-validation set to true by default.

Workarounds​

Starting with Nginx version v1.8.0, ingress administrators can set the --strict-validate-path-type flag to true to validate ingress rules having pathType as "Exact" or "Prefix". If the pathType is ImplementationSpecific then an admission controller policy is required to filter out the malicious path.

September 01, 2023 - CVE-2023-22809 Sudo Vulnerability - 7.8 CVSS​

The sudo program version 1.9.12p2 and earlier mishandles extra arguments passed in the user-provided environment variables SUDO_EDITOR, VISUAL, and EDITOR when the sudoedit command is executed.

The mishandling allows a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain the -- argument that defeats a protection mechanism. For example, an attacker may issue the following command EDITOR='vim -- /path/to/extra/file value.

Impact​

This vulnerability affects the following Palette components:

  • Self-hosted Palette instances with versions older than 4.0.0

  • Private Cloud Gateways instances with versions older than 4.0.0

  • Clusters deployed with Palette versions older than 4.0.0

Patches​

September 01, 2023 - CVE-2023-24538 - HTML Template Vulnerability - Security Advisory - 9.8 CVSS​

Go templates do not consider backticks as a Javascript string delimiter and, as a result, do not escape them as expected. Backticks have been used since ES6 for JS template literals. If a Go template contains an action within a literal Javascript template, the action's contents can be used to terminate the literal and potentially inject arbitrary Javascript code into the Go template.

Go template actions are disallowed from being used inside of them, for example, "var a = {{.}}" since there is no safe way to allow this behavior. This takes the same approach as github.com/google/safehtml. With this fix, Template.Parse() returns an error when it encounters templates containing actions with literal JavaScript. The ErrorCode has a value of 12. This ErrorCode is currently unexported but will be exported in the release of Go 1.21. Users who rely on the previous behavior can re-enable it using the GODEBUG flag jstmpllitinterp=1 with the caveat that backticks will now be escaped.

August 4, 2022 - CVE-2022-1292 c_rehash script vulnerability in vSphere CSI pack - 9.8 CVSS​

On May 3 2022, OpenSSL published a security advisory disclosing a command injection vulnerability in the c_rehash script included with the OpenSSL library. Some operating systems automatically execute this script as a part of normal operations, which could allow an attacker to execute arbitrary commands with elevated privileges.

Palette is not directly affected by this vulnerability. However, if your cluster profile is using the vSphere CSI pack, version v2.3 or below, it contains a vulnerable version of the c_rehash script.

Impact​

The c_rehash script does not sanitize shell metacharacters properly to prevent command injection. This script is distributed by some operating systems, and by extension, in container images, in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script.

Resolution​

This vulnerability has been addressed in the vSphere CSI pack greater than or equal to version v2.6.

Workarounds​

Update cluster profiles using the vSphere CSI pack to version v2.6 or greater. Apply the updated cluster profile changes to all clusters consuming the cluster profile.
