CVE-2021-33054 2 Debian, Inverse 2 Debian Linux, Sogo 2024-08-03 7.5 High
SOGo 2.x before 2.4.1 and 3.x through 5.x before 5.1.1 does not validate the signatures of any SAML assertions it receives. Any actor with network access to the deployment could impersonate users when SAML is the authentication method. (Only versions after 2.0.5a are affected.)
CVE-2021-32977 1 Aveva 1 System Platform 2024-08-03 7.2 High
AVEVA System Platform versions 2017 through 2020 R2 P01 does not verify, or incorrectly verifies, the cryptographic signature for data.
CVE-2021-32738 1 Stellar 1 Js-stellar-sdk 2024-08-03 6.5 Medium
js-stellar-sdk is a Javascript library for communicating with a Stellar Horizon server. The `Utils.readChallengeTx` function used in SEP-10 Stellar Web Authentication states in its function documentation that it reads and validates the challenge transaction including verifying that the `serverAccountID` has signed the transaction. In js-stellar-sdk before version 8.2.3, the function does not verify that the server has signed the transaction. Applications that also used `Utils.verifyChallengeTxThreshold` or `Utils.verifyChallengeTxSigners` to verify the signatures including the server signature on the challenge transaction are unaffected as those functions verify the server signed the transaction. Applications calling `Utils.readChallengeTx` should update to version 8.2.3, the first version with a patch for this vulnerability, to ensure that the challenge transaction is completely valid and signed by the server creating the challenge transaction.
CVE-2021-32685 1 Togatech 1 Tenvoy 2024-08-03 9.8 Critical
tEnvoy contains the PGP, NaCl, and PBKDF2 in node.js and the browser (hashing, random, encryption, decryption, signatures, conversions), used by TogaTech.org. In versions prior to 7.0.3, the `verifyWithMessage` method of `tEnvoyNaClSigningKey` always returns `true` for any signature that has a SHA-512 hash matching the SHA-512 hash of the message even if the signature was invalid. This issue is patched in version 7.0.3. As a workaround: In `tenvoy.js` under the `verifyWithMessage` method definition within the `tEnvoyNaClSigningKey` class, ensure that the return statement call to `this.verify` ends in `.verified`.
CVE-2021-31847 1 Mcafee 1 Agent 2024-08-03 8.2 High
Improper access control vulnerability in the repair process for McAfee Agent for Windows prior to 5.7.4 could allow a local attacker to perform a DLL preloading attack using unsigned DLLs. This would result in elevation of privileges and the ability to execute arbitrary code as the system user, through not correctly protecting a temporary directory used in the repair process and not checking the DLL signature.
CVE-2021-31841 1 Mcafee 1 Mcafee Agent 2024-08-03 8.2 High
A DLL sideloading vulnerability in McAfee Agent for Windows prior to 5.7.4 could allow a local user to perform a DLL sideloading attack with an unsigned DLL with a specific name and in a specific location. This would result in the user gaining elevated permissions and the ability to execute arbitrary code as the system user, through not checking the DLL signature.
CVE-2021-30246 1 Jsrsasign Project 1 Jsrsasign 2024-08-03 9.1 Critical
In the jsrsasign package through 10.1.13 for Node.js, some invalid RSA PKCS#1 v1.5 signatures are mistakenly recognized to be valid. NOTE: there is no known practical attack.
CVE-2021-30130 2 Debian, Phpseclib 2 Debian Linux, Phpseclib 2024-08-03 7.5 High
phpseclib before 2.0.31 and 3.x before 3.0.7 mishandles RSA PKCS#1 v1.5 signature verification.
CVE-2021-30066 2 Belden, Schneider-electric 26 Eagle 20 Tofino 943 987-501-tx\/tx, Eagle 20 Tofino 943 987-501-tx\/tx Firmware, Eagle 20 Tofino 943 987-502 -tx\/mm and 23 more 2024-08-03 6.8 Medium
On Schneider Electric ConneXium Tofino Firewall TCSEFEA23F3F22 before 03.23, TCSEFEA23F3F20/21, and Belden Tofino Xenon Security Appliance, an arbitrary firmware image can be loaded because firmware signature verification (for a USB stick) can be bypassed. NOTE: this issue exists because of an incomplete fix of CVE-2017-11400.
CVE-2021-29957 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-08-03 4.3 Medium
If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an additional unprotected part, Thunderbird did not indicate that only parts of the message are protected. This vulnerability affects Thunderbird < 78.10.2.
CVE-2021-29500 1 Bubble Fireworks Project 1 Bubble Fireworks 2024-08-03 7.5 High
bubble fireworks is an open source java package relating to Spring Framework. In bubble fireworks before version 2021.BUILD-SNAPSHOT there is a vulnerability in which the package did not properly verify the signature of JSON Web Tokens. This allows to forgery of valid JWTs.
CVE-2021-29455 1 Grassroot 1 Grassroot Platform 2024-08-03 7.5 High
Grassroot Platform is an application to make it faster, cheaper and easier to persistently organize and mobilize people in low-income communities. Grassroot Platform before master deployment as of 2021-04-16 did not properly verify the signature of JSON Web Tokens when refreshing an existing JWT. This allows to forge a valid JWT. The problem has been patched in version 1.3.1 by deprecating the JWT refresh function, which was an overdue deprecation regardless (the "refresh" flow is no longer used).
CVE-2021-29451 1 Manydesigns 1 Portofino 2024-08-03 9.1 Critical
Portofino is an open source web development framework. Portofino before version 5.2.1 did not properly verify the signature of JSON Web Tokens. This allows forging a valid JWT. The issue will be patched in the upcoming 5.2.1 release.
CVE-2021-28091 4 Debian, Entrouvert, Fedoraproject and 1 more 4 Debian Linux, Lasso, Fedora and 1 more 2024-08-03 7.5 High
Lasso all versions prior to 2.7.0 has improper verification of a cryptographic signature.
CVE-2021-25636 3 Fedoraproject, Libreoffice, Redhat 3 Fedora, Libreoffice, Enterprise Linux 2024-08-03 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-2021-23992 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-08-03 4.3 Medium
Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-23991 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-08-03 6.8 Medium
If a Thunderbird user has previously imported Alice's OpenPGP key, and Alice has extended the validity period of her key, but Alice's updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice's key with an invalid subkey, Thunderbird might subsequently attempt to use the invalid subkey, and will fail to send encrypted email to Alice. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-23993 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-08-03 6.5 Medium
An attacker may perform a DoS attack to prevent a user from sending encrypted email to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self signature, and the Thunderbird user imports the crafted key, then Thunderbird may try to use the invalid subkey, but the RNP library rejects it from being used, causing encryption to fail. This vulnerability affects Thunderbird < 78.9.1.

Improper Verification of Cryptographic Signature vulnerability exists inhomeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior which could allow remote code execution when unauthorized code is copied to the device.
CVE-2021-22734 1 Schneider-electric 4 Homelynk, Homelynk Firmware, Spacelynk and 1 more 2024-08-03 7.2 High
Improper Verification of Cryptographic Signature vulnerability exists in homeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior which could cause remote code execution when an attacker loads unauthorized code.
