CVSS: 9.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-49569 – Maliciously crafted Git server replies can lead to path traversal and RCE on go-git clients
https://notcve.org/view.php?id=CVE-2023-49569
A path traversal vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to create and amend files across the filesystem. In the worse case scenario, remote code execution could be achieved. Applications are only affected if they are using the ChrootOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS , which is the default when using "Plain" versions of Open and Clone funcs (e.g. PlainClone). Applications using BoundOS https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS or in-memory filesystems are not affected by this issue. This is a go-git implementation issue and does not affect the upstream git cli. • https://github.com/go-git/go-git/security/advisories/GHSA-449p-3h89-pw88 https://access.redhat.com/security/cve/CVE-2023-49569 https://bugzilla.redhat.com/show_bug.cgi?id=2258143 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-49568 – Maliciously crafted Git server replies can cause DoS on go-git clients
https://notcve.org/view.php?id=CVE-2023-49568
A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients. Applications using only the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git implementation issue and does not affect the upstream git cli. Se descubrió una vulnerabilidad de denegación de servicio (DoS) en versiones de go-git anteriores a la v5.11. Esta vulnerabilidad permite a un atacante realizar ataques de denegación de servicio proporcionando respuestas especialmente manipuladas desde un servidor Git que provoca el agotamiento de los recursos en los clientes go-git. Las aplicaciones que utilizan únicamente el sistema de archivos en memoria compatible con go-git no se ven afectadas por esta vulnerabilidad. • https://github.com/go-git/go-git/security/advisories/GHSA-mw99-9chc-xw7r https://access.redhat.com/security/cve/CVE-2023-49568 https://bugzilla.redhat.com/show_bug.cgi?id=2258165 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
