CVE-2022-22576 – curl: OAUTH2 bearer bypass in connection re-use
https://notcve.org/view.php?id=CVE-2022-22576
An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). Se presenta una vulnerabilidad de autenticación inapropiada en curl versiones 7.33.0 hasta 7.82.0 incluyéndola, que podría permitir reúso de conexiones autenticadas por OAUTH2 sin asegurarse apropiadamente de que la conexión fue autenticada con las mismas credenciales establecidas para esta transferencia. Esto afecta a los protocolos con SASL: SMPTP(S), IMAP(S), POP3(S) y LDAP(S) (sólo openldap) A vulnerability was found in curl. This security flaw allows reusing OAUTH2-authenticated connections without properly ensuring that the connection was authenticated with the same credentials set for this transfer. • https://hackerone.com/reports/1526328 https://lists.debian.org/debian-lts-announce/2022/08/msg00017.html https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20220609-0008 https://www.debian.org/security/2022/dsa-5197 https://access.redhat.com/security/cve/CVE-2022-22576 https://bugzilla.redhat.com/show_bug.cgi?id=2077541 • CWE-287: Improper Authentication CWE-295: Improper Certificate Validation CWE-306: Missing Authentication for Critical Function •
CVE-2021-3422 – Indexer denial-of-service via malformed S2S request
https://notcve.org/view.php?id=CVE-2021-3422
The lack of validation of a key-value field in the Splunk-to-Splunk protocol results in a denial-of-service in Splunk Enterprise instances configured to index Universal Forwarder traffic. The vulnerability impacts Splunk Enterprise versions before 7.3.9, 8.0 versions before 8.0.9, and 8.1 versions before 8.1.3. It does not impact Universal Forwarders. When Splunk forwarding is secured using TLS or a Token, the attack requires compromising the certificate or token, or both. Implementation of either or both reduces the severity to Medium. • https://claroty.com/2022/03/24/blog-research-locking-down-splunk-enterprise-indexers-and-forwarders https://www.splunk.com/en_us/product-security/announcements/svd-2022-0301.html • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
