CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 2CVE-2021-29923 – golang: net: incorrect parsing of extraneous zero characters at the beginning of an IP address octet
https://notcve.org/view.php?id=CVE-2021-29923
Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR. Go versiones anteriores a 1.17, no considera apropiadamente los caracteres cero extraños al principio de un octeto de dirección IP, lo que (en algunas situaciones) permite a atacantes omitir el control de acceso que es basado en las direcciones IP, debido a una interpretación octal inesperada. Esto afecta a net.ParseIP y net.ParseCIDR A flaw was found in golang. Extraneous zero characters at the beginning of an IP address octet are not properly considered which could allow an attacker to bypass IP-based access controls. • https://defcon.org/html/defcon-29/dc-29-speakers.html#kaoudis https://github.com/golang/go/issues/30999 https://github.com/golang/go/issues/43389 https://github.com/sickcodes/security/blob/master/advisories/SICK-2021-016.md https://go-review.googlesource.com/c/go/+/325829 https://golang.org/pkg/net/#ParseCIDR https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4CHKSFMHZVOBCZSSVRE3UEYNKARTBMTM https://security.gentoo.org/glsa/202208-02 https: • CWE-20: Improper Input Validation •

The encoding/xml package in Go (all versions) does not correctly preserve the semantics of attribute namespace prefixes during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications. El paquete encoding/xml en Go (todas las versiones) no conserva correctamente la semántica de los prefijos del espacio de nombres de atributos durante los viajes de ida por vuelta del proceso de generación de token, que permite a un atacante diseñar entradas que se comportan de manera conflictiva durante las diferentes etapas del procesamiento en las aplicaciones previas afectadas • https://github.com/mattermost/xml-roundtrip-validator/blob/master/advisories/unstable-attributes.md https://security.netapp.com/advisory/ntap-20210129-0006 • CWE-115: Misinterpretation of Input •
