Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2021-3712
High

W OpenSSL, struktura ASN1_STRING, która przechowuje dane ciągu ASN.1, może nie być poprawnie zakończona znakiem NUL. Aplikacje mogą tworzyć poprawne struktury ASN1_STRING, które nie kończą się tym znakiem, co prowadzi do potencjalnych problemów z bezpieczeństwem w funkcjach drukujących dane ASN.1.

CVE-2021-39144
HighActively exploited

XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker with sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

CVE-2021-39302
CriticalEPSS 56%

MISP version 2.4.148, in certain configurations, allows SQL injection via the $conditions['org'] value in the app/Model/Log.php file.

CVE-2021-35395
CriticalActively exploited

Realtek Jungle SDK versions v2.x through v3.4.14B includes an HTTP web server exposing a management interface (webs or boa) that is affected by multiple stack buffer overflows and arbitrary command execution flaws. The issues occur in functions such as formRebootCheck, formWsc, formWlanMultipleAP, formWlSiteSurvey, formStaticDHCP, and formSysCmd due to unsafe copying of parameters like submit-url, ifname, hostname, peerPin, and sysCmd. Successful exploitation allows remote attackers to achieve arbitrary code execution on the device.

CVE-2021-35394
CriticalActively exploited

Realtek Jungle SDK version v2.x up to v3.4.14B provides a diagnostic tool called 'MP Daemon' that is usually compiled as 'UDPServer' binary. The binary is affected by multiple memory corruption vulnerabilities and an arbitrary command injection vulnerability that can be exploited by remote unauthenticated attackers.

CVE-2021-26086
MediumActively exploited

Affected versions of Atlassian Jira Server and Data Center allow remote attackers to read particular files via a path traversal vulnerability in the /WEB-INF/web.xml endpoint. The affected versions are before version 8.5.14, from version 8.6.0 before 8.13.6, and from version 8.14.0 before 8.16.1.

CVE-2021-36380
CriticalActively exploited

Sunhillo SureLine before 8.7.0.1.1 allows Unauthenticated OS Command Injection via shell metacharacters in ipAddr or dnsAddr /cgi/networkDiag.cgi.

CVE-2021-37345
High
