CVE-2020-16150 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2024-11-21 5.5 Medium
A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length.
CVE-2020-15392 1 Venki 1 Supravizio Bpm 2024-11-21 5.3 Medium
A user enumeration vulnerability flaw was found in Venki Supravizio BPM 10.1.2. This issue occurs during password recovery, where a difference in error messages could allow an attacker to determine if a username is valid or not, enabling a brute-force attack with valid usernames.
CVE-2020-15237 1 Shrinerb 1 Shrine 2024-11-21 5.9 Medium
In Shrine before version 3.3.0, when using the `derivation_endpoint` plugin, it's possible for the attacker to use a timing attack to guess the signature of the derivation URL. The problem has been fixed by comparing sent and calculated signature in constant time, using `Rack::Utils.secure_compare`. Users using the `derivation_endpoint` plugin are urged to upgrade to Shrine 3.3.0 or greater. A possible workaround is provided in the linked advisory.
CVE-2020-15151 2 Magento, Openmage 2 Magento, Openmage Long Term Support 2024-11-21 8 High
OpenMage LTS before versions 19.4.6 and 20.0.2 allows attackers to circumvent the `fromkey protection` in the Admin Interface and increases the attack surface for Cross Site Request Forgery attacks. This issue is related to Adobe's CVE-2020-9690. It is patched in versions 19.4.6 and 20.0.2.
CVE-2020-14145 3 Netapp, Openbsd, Redhat 11 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 8 more 2024-11-21 5.9 Medium
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
CVE-2020-14002 3 Fedoraproject, Netapp, Putty 3 Fedora, Oncommand Unified Manager Core Package, Putty 2024-11-21 5.9 Medium
PuTTY 0.68 through 0.73 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client).
CVE-2020-13998 1 Citrix 1 Xenapp 2024-11-21 5.3 Medium
Citrix XenApp 6.5, when 2FA is enabled, allows a remote unauthenticated attacker to ascertain whether a user exists on the server, because the 2FA error page only occurs after a valid username is entered. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
CVE-2020-13844 2 Arm, Opensuse 15 Cortex-a32, Cortex-a32 Firmware, Cortex-a34 and 12 more 2024-11-21 5.5 Medium
Arm Armv8-A core implementations utilizing speculative execution past unconditional changes in control flow may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka "straight-line speculation."
CVE-2020-13413 1 Aviatrix 2 Controller, Vpn Client 2024-11-21 5.3 Medium
An issue was discovered in Aviatrix Controller before 5.4.1204. There is a Observable Response Discrepancy from the API, which makes it easier to perform user enumeration via brute force.
CVE-2020-12912 1 Amd 1 Energy Driver For Linux 2024-11-21 5.5 Medium
A potential vulnerability in the AMD extension to Linux "hwmon" service may allow an attacker to use the Linux-based Running Average Power Limit (RAPL) interface to show various side channel attacks. In line with industry partners, AMD has updated the RAPL interface to require privileged access.
CVE-2020-12788 1 Microchip 152 Atsama5d21c-cu, Atsama5d21c-cu Firmware, Atsama5d21c-cur and 149 more 2024-11-21 7.5 High
CMAC verification functionality in Microchip Atmel ATSAMA5 products is vulnerable to vulnerable to timing and power analysis attacks.
CVE-2020-12413 1 Mozilla 2 Firefox, Firefox Esr 2024-11-21 5.9 Medium
The Raccoon attack is a timing attack on DHE ciphersuites inherit in the TLS specification. To mitigate this vulnerability, Firefox disabled support for DHE ciphersuites.
CVE-2020-12402 5 Debian, Fedoraproject, Mozilla and 2 more 6 Debian Linux, Fedora, Firefox and 3 more 2024-11-21 4.4 Medium
During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78.
CVE-2020-12401 2 Mozilla, Redhat 3 Firefox, Enterprise Linux, Openshift Do 2024-11-21 4.7 Medium
During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-12400 2 Mozilla, Redhat 3 Firefox, Enterprise Linux, Openshift Do 2024-11-21 4.7 Medium
When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-12399 3 Debian, Mozilla, Redhat 5 Debian Linux, Firefox, Firefox Esr and 2 more 2024-11-21 4.4 Medium
NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
CVE-2020-11735 1 Wolfssl 1 Wolfssl 2024-11-21 5.3 Medium
The private-key operations in ecc.c in wolfSSL before 4.4.0 do not use a constant-time modular inverse when mapping to affine coordinates, aka a "projective coordinates leak."
CVE-2020-11713 1 Wolfssl 1 Wolfssl 2024-11-21 7.5 High
wolfSSL 4.3.0 has mulmod code in wc_ecc_mulmod_ex in ecc.c that does not properly resist timing side-channel attacks.
CVE-2020-11683 1 Linux4sam 1 At91bootstrap 2024-11-21 6.8 Medium
A timing side channel was discovered in AT91bootstrap before 3.9.2. It can be exploited by attackers with physical access to forge CMAC values and subsequently boot arbitrary code on an affected system.
CVE-2020-11625 1 Avertx 4 Hd438, Hd438 Firmware, Hd838 and 1 more 2024-11-21 5.3 Medium
An issue was discovered in AvertX Auto focus Night Vision HD Indoor/Outdoor IP Dome Camera HD838 and Night Vision HD Indoor/Outdoor Mini IP Bullet Camera HD438. Failed web UI login attempts elicit different responses depending on whether a user account exists. Because the responses indicate whether a submitted username is valid or not, they make it easier to identify legitimate usernames. If a login request is sent to ISAPI/Security/sessionLogin/capabilities using a username that exists, it will return the value of the salt given to that username, even if the password is incorrect. However, if a login request is sent using a username that is not present in the database, it will return an empty salt value. This allows attackers to enumerate legitimate usernames, facilitating brute-force attacks. NOTE: this is different from CVE-2020-7057.
