Jenkins NeuVector Vulnerability Scanner Plugin 1.22 and earlier does not perform a permission check in a connection test HTTP endpoint. This allows attackers with Overall/Read permission to connect to an attacker-specified hostname and port using attacker-specified username and password. Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. NeuVector Vulnerability Scanner Plugin 2.2 requires POST requests and Overall/Administer permission for the affected HTTP endpoint.

Jenkins MATLAB Plugin determines whether a user-specified directory on the Jenkins controller is the location of a MATLAB installation by parsing an XML file in that directory. MATLAB Plugin 2.11.0 and earlier does not perform permission checks in several HTTP endpoints implementing related form validation. Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. Additionally, the plugin does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows attackers able to create files on the Jenkins controller file system to have Jenkins parse a crafted XML document that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery. MATLAB Plugin 2.11.1 configures its XML parser to prevent XML external entity (XXE) attacks. Additionally, POST requests and Item/Configure permission are required for the affected HTTP endpoints.

Jenkins Jira Plugin 3.11 and earlier does not set the appropriate context for credentials lookup, allowing the use of system-scoped credentials otherwise reserved for the global configuration. This allows attackers with Item/Configure permission to access and capture credentials they are not entitled to. Jira Plugin 3.12 defines the appropriate context for credentials lookup.

Jenkins Google Compute Engine Plugin 4.550.vb_327fca_3db_11 and earlier does not correctly perform permission checks in multiple HTTP endpoints. This allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to do the following: - Enumerate system-scoped credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability. - Connect to Google Cloud Platform using attacker-specified credentials IDs obtained through another method, to obtain information about existing projects. Google Compute Engine Plugin 4.551.v5a_4dc98f6962 requires Overall/Administer permission for the affected HTTP endpoints.

A serialization vulnerability in logback receiver component part of logback version 1.4.11 allows an attacker to mount a Denial-Of-Service attack by sending poisoned data.

### Impact Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. ### Patches No patch is yet available, however work is underway to migrate to a fully constant-time implementation. ### Workarounds The only currently available workaround is to avoid using the `rsa` crate in settings where attackers are able to observe timing information, e.g. local use on a non-compromised computer is fine. ### References This vulnerability was discovered as part of the "Marvin Attack", which revealed several implementations of RSA including OpenSSL had not properly mitigated timing sidechannel attacks. - https://rustsec.org/advisories/RUSTSEC-2023-0071.html - https://people.redhat.com/~hkario/marvin/ - https://github.com/RustCrypto/RSA/issues/19

The [Marvin Attack] is a timing sidechannel vulnerability which allows performing RSA decryption and signing operations as an attacker with the ability to observe only the time of the decryption operation performed withthe private key. A recent survey of RSA implementations found that the Rust `rsa` crate is one of many implementations vulnerable to this attack. No fixed version is available at this time.

This function returned a reference into an OpenSSL datastructure, but there was no way to ensure OpenSSL would not mutate the datastructure behind one's back. Use of this function should be replaced with `X509StoreRef::all_certificates`.

### Summary Calling `load_pem_pkcs7_certificates` or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference and segfault. ### PoC Here is a Python code that triggers the issue: ```python from cryptography.hazmat.primitives.serialization.pkcs7 import load_der_pkcs7_certificates, load_pem_pkcs7_certificates pem_p7 = b""" -----BEGIN PKCS7----- MAsGCSqGSIb3DQEHAg== -----END PKCS7----- """ der_p7 = b"\x30\x0B\x06\x09\x2A\x86\x48\x86\xF7\x0D\x01\x07\x02" load_pem_pkcs7_certificates(pem_p7) load_der_pkcs7_certificates(der_p7) ``` ### Impact Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to deserialize a PKCS7 blob/certificate. The consequences extend to potential disruptions in system availability and stability.
