IBM WebSphere Application Server Liberty 18.0.0.2 through 24.0.0.4 is vulnerable to a denial of service, caused by sending a specially crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. IBM X-Force ID: 284574.

IBM WebSphere Application Server 8.5, 9.0 and IBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.4 are vulnerable to a denial of service, caused by sending a specially crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. IBM X-Force ID: 281516.

A ReDoS (regular expression denial of service) flaw was found in the tough-cookie module before 2.3.3 for Node.js. An attacker that is able to make an HTTP request using a specially crafted cookie may cause the application to consume an excessive amount of CPU.

An unspecified error in with TrustCor's ownership also operated a business that produced spyware in Certifi has an unknown impact and attack vector.

Summary

If a user is granted the admin:users scope, they may escalate their own privileges by making themselves a full admin user.

Details

The admin:users scope allows a user to edit user records:

admin:users Read, write, create and delete users and their authentication state, not including their servers or tokens. -- https://jupyterhub.readthedocs.io/en/stable/rbac/scopes.html#available-scopes

However, this includes making users admins. Admin users are granted scopes beyond admin:users making this a mechanism by which granted scopes may be escalated.

Impact

The impact is relatively small in that admin:users is already an extremely privileged scope only granted to trusted users. In effect, admin:users is equivalent to admin=True, which is not intended.

Note that the change here only prevents escalation to the built-in JupyterHub admin role that has unrestricted permissions. It does not prevent users with e.g. groups permissions from granting themselves or other users permissions via group membership, which is intentional.

IBM WebSphere Application Server 8.5, 9.0 and IBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.5 are vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information, consume memory resources, or to conduct a server-side request forgery attack. IBM X-Force ID: 280401.

GNU Emacs could allow a remote attacker to execute arbitrary code on the system, caused by a code injection flaw in org-link-expand-abbrev in lisp/ol.el. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.

Apache Solr could allow a remote attacker to bypass security restrictions, caused by improper authentication validation when using PKIAuthenticationPlugin. By sending a specially crafted request using a fake URL Path ending, an attacker could exploit this vulnerability to bypass access restriction.

A security vulnerability was found in zlib. The flaw triggered a heap-based buffer in inflate in the inflate.c function via a large gzip header extra field. This flaw is only applicable in the call inflateGetHeader.

IBM Informix Dynamic Server 12.10 and 14.10 onsmsync is vulnerable to a heap buffer overflow, caused by improper bounds checking which could allow an attacker to execute arbitrary code. IBM X-Force ID: 250753.

Apache Solr could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure default initialization of resource flaw. By sending a specially crafted request, an attacker could exploit this vulnerability to load custom code into classloaders.

GNU Emacs could provide weaker than expected security, caused by an issue with contents of remote files to be trusted in Org mode. A remote attacker could exploit this vulnerability to launch further attacks on the system.

IBM Cognos Analytics 11.2.0 through 11.2.4 FP5 and 12.0.0 through 12.0.4 could allow a remote attacker to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system.

IBM Cognos Analytics 11.2.0 through 11.2.4 FP5 is vulnerable to local file inclusion vulnerability, allowing an attacker to access sensitive files by inserting path traversal payloads inside the deficon parameter.

IBM Informix Dynamic Server 12.10 and 14.10 archecker is vulnerable to a heap buffer overflow, caused by improper bounds checking which could allow a local user to cause a segmentation fault. IBM X-Force ID: 251204.

IBM Informix Dynamic Server 12.10 and 14.10 cdr is vulnerable to a heap buffer overflow, caused by improper bounds checking which could allow a local user to cause a segmentation fault. IBM X-Force ID: 251206.

GNU Emacs could provide weaker than expected security, caused by an issue with treating inline MIME contents as trusted. A remote attacker could exploit this vulnerability to launch further attacks on the system.

GNU Emacs could provide weaker than expected security, caused by an issue with LaTeX preview is enabled by default for e-mail attachments. A remote attacker could exploit this vulnerability to launch further attacks on the system.
