CVSS: 8.1EPSS: 0%CPEs: 2EXPL: 1CVE-2023-31484 – perl: CPAN.pm does not verify TLS certificates when downloading distributions over HTTPS
https://notcve.org/view.php?id=CVE-2023-31484
CPAN.pm before 2.35 does not verify TLS certificates when downloading distributions over HTTPS. A flaw was found in Perl's CPAN, which doesn't check TLS certificates when downloading content. This happens due to `verify_SSL` missing when suing the `HTTP::Tiny` library during the connection. This may allow an attacker to inject into the network path and perform a Man-In-The-Middle attack, causing confidentiality or integrity issues. • http://www.openwall.com/lists/oss-security/2023/04/29/1 http://www.openwall.com/lists/oss-security/2023/05/03/3 http://www.openwall.com/lists/oss-security/2023/05/03/5 http://www.openwall.com/lists/oss-security/2023/05/07/2 https://blog.hackeriet.no/perl-http-tiny-insecure-tls-default-affects-cpan-modules https://github.com/andk/cpanpm/pull/175 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BM6UW55CNFUTNGD5ZRKGUKKKFDJGMFHL https:& • CWE-295: Improper Certificate Validation •

Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading. Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value. Encode.pm, distribuido en Perl versiones hasta 5.34.0, permite a usuarios locales alcanzar privilegios por medio de una biblioteca Encode::ConfigLocal (en el directorio de trabajo actual) que se adelanta a una carga dinámica de módulos. Una explotación requiere una configuración inusual, y determinadas versiones 2021 de Encode.pm (3.05 hasta 3.11). • https://github.com/Perl/perl5/commit/c1a937fef07c061600a0078f4cb53fe9c2136bb9 https://github.com/dankogai/p5-encode/commit/527e482dc70b035d0df4f8c77a00d81f8d775c74 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5NDGQSGMEZ75FJGBKNYC75OTO7TF7XHB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6KOZYD7BH2DNIAEZ2ZL4PJ4QUVQI6Y33 https://metacpan.org/dist/Encode/changes https://news.cpanel.com/unscheduled-tsr-10-august-2021 https://security-tracker.debian.org/tracker • CWE-427: Uncontrolled Search Path Element •

An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference. Se detectó un problema en el módulo DBI versiones anteriores a 1.643 para Perl. La documentación de la función hv_fetch() requiere comprobación para NULL y el código lo hace. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00013.html https://github.com/perl5-dbi/dbi/commit/eca7d7c8f43d96f6277e86d1000e842eb4cc67ff https://lists.debian.org/debian-lts-announce/2020/09/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JXLKODJ7B57GITDEZZXNSHPK4VBYXYHR https://metacpan.org/pod/distribution/DBI/Changes#Changes-in-DBI-1.643-... https://usn.ubun • CWE-476: NULL Pointer Dereference •

An issue was discovered in the DBI module through 1.643 for Perl. DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute in the data source name (DSN). NOTE: this issue exists because of an incomplete fix for CVE-2014-10401. Se detectó un problema en el módulo DBI versiones hasta 1.643 para Perl. Los controladores DBD::File pueden abrir archivos de carpetas distintas de las que son pasadas específicamente por medio del atributo f_dir en el data source name (DSN). • https://lists.debian.org/debian-lts-announce/2022/05/msg00046.html https://rt.cpan.org/Public/Bug/Display.html?id=99508#txn-1911590 • CWE-732: Incorrect Permission Assignment for Critical Resource •
