CVE-2021-27899 1 Proofpoint 1 Insider Threat Management 2024-11-21 7.4 High
The Proofpoint Insider Threat Management Agents (formerly ObserveIT Agent) for MacOS and Linux perform improper validation of the ITM Server's certificate, which enables a remote attacker to intercept and alter these communications using a man-in-the-middle attack. All versions before 7.11.1 are affected. Agents for Windows and Cloud are not affected.
CVE-2021-27768 1 Hcltech 1 Verse 2024-11-21 6.3 Medium
Using the ability to perform a Man-in-the-Middle (MITM) attack, which indicates a lack of hostname verification, sensitive account information was able to be intercepted. In this specific scenario, the application's network traffic was intercepted using a proxy server set up in 'transparent' mode while a certificate with an invalid hostname was active. The Android application was found to have hostname verification issues during the server setup and login flows; however, the application did not process requests post-login.

CVE-2021-27098 1 Cncf 1 Spire 2024-11-21 8.1 High
In SPIRE 0.8.1 through 0.8.4 and before versions 0.9.4, 0.10.2, 0.11.3 and 0.12.1, specially crafted requests to the FetchX509SVID RPC of SPIRE Server’s Legacy Node API can result in the possible issuance of an X.509 certificate with a URI SAN for a SPIFFE ID that the agent is not authorized to distribute. Proper controls are in place to require that the caller presents a valid agent certificate that is already authorized to issue at least one SPIFFE ID, and the requested SPIFFE ID belongs to the same trust domain, prior to being able to trigger this vulnerability. This issue has been fixed in SPIRE versions 0.8.5, 0.9.4, 0.10.2, 0.11.3 and 0.12.1.

CVE-2021-25636 3 Fedoraproject, Libreoffice, Redhat 3 Fedora, Libreoffice, Enterprise Linux 2024-11-21 7.5 High
LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to create a digitally signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the document to contain both "X509Data" and "KeyValue" children of the "KeyInfo" tag, which when opened caused LibreOffice to verify using the "KeyValue" but to report verification with the unrelated "X509Data" value. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.5.
CVE-2021-25634 3 Debian, Libreoffice, Redhat 3 Debian Linux, Libreoffice, Enterprise Linux 2024-11-21 7.5 High
LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to modify a digitally signed ODF document to insert an additional signing time timestamp which LibreOffice would incorrectly present as a valid signature signed at the bogus signing time. This issue affects: The Document Foundation LibreOffice 7-0 versions prior to 7.0.6; 7-1 versions prior to 7.1.2.
CVE-2021-25633 3 Debian, Libreoffice, Redhat 3 Debian Linux, Libreoffice, Enterprise Linux 2024-11-21 7.5 High
LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to create a digitally signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the document to combine multiple certificate data, which when opened caused LibreOffice to display a validly signed indicator but whose content was unrelated to the signature shown. This issue affects: The Document Foundation LibreOffice 7-0 versions prior to 7.0.6; 7-1 versions prior to 7.1.2.
CVE-2021-24012 1 Fortinet 1 Fortios 2024-11-21 6.5 Medium
