Latest f5 NGINX Instance Manager CVEs

Newest publication first

  1. HighCVSS 8.8 EPSS 0.74%

    NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_slice_module module. When the slice directive and unnamed regex captures are configured or when a background cache update happens, unauthenticated attackers can send requests that may cause uninitialized memory...

  2. MediumCVSS 5.3 EPSS 0.30%

    The NGINX Agent config_dirs directive allows a low-privileged attacker to gain limited read and write access to files outside of the designated secure directory. The config_dirs directive required for this issue can also be configured through NGINX Instance Manager. A successful...

  3. CriticalCVSS 9.2 EPSS 6.2%

    NGINX Open Source has a vulnerability in the ngx_http_v3_module module. When NGINX Open Source is configured to use the HTTP/3 QUIC module, a remote unauthenticated attacker along with conditions beyond their control can use a specially crafted HTTP/3 session to reopen a QPACK en...

  4. MediumCVSS 6.3 EPSS 0.68%

    NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module. When content is served or proxied through a location block with both source_charset utf-8; and a charset directive (for example, charset koi8-r;) configured, remote, unauthenticated attac...

  5. CriticalCVSS 9.2 EPSS 10.9%

    NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when a rewrite directive uses a regex pattern with distinct, overlapping Perl-Compatible Regular Expression (PCRE) captures (for example, ^/((.*))$) and a replac...

  6. MediumCVSS 6.9 EPSS 0.37%

    When NGINX Plus or NGINX Open Source are configured to use the HTTP/3 QUIC module, an attacker may be able to spoof their source IP address allowing for bypass of authorization or bypass of rate limiting. Note: Software versions which have reached End of Technical Support (EoTS)...

  7. MediumCVSS 6.3 EPSS 0.35%

    When NGINX Open Source is configured to proxy HTTP/2 traffic by setting proxy_http_version to 2, and also uses proxy_set_body, an attacker may be able to inject frame headers and payload bytes to the upstream peer. Note: Software versions which have reached End of Technical Suppo...

  8. MediumCVSS 6.3 EPSS 0.73%

    NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module. When charset, source_charset, and charset_map and proxy_pass with disabled buffering ("off") directives are configured, unauthenticated attackers can send requests that with conditions be...

  9. MediumCVSS 6.3 EPSS 0.69%

    NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_ssl_module module when the ssl_verify_client directive is set to "on" or "optional," and the ssl_ocsp directive is set to "on" or the leaf parameters are configured with a resolver. With this configuration, an...

  10. CriticalCVSS 9.2 EPSS 68.0%

    NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when the rewrite directive is followed by a rewrite, if, or set directive and an unnamed Perl-Compatible Regular Expression (PCRE) capture (for example, $1, $2)...

  11. HighCVSS 8.2 EPSS 0.38%

    A vulnerability exists in NGINX OSS and NGINX Plus when configured to proxy to upstream Transport Layer Security (TLS) servers. An attacker with a man-in-the-middle (MITM) position on the upstream server side—along with conditions beyond the attacker's control—may be able to inje...

  12. MediumCVSS 5.1 EPSS 0.37%

    A session fixation issue was discovered in the NGINX OpenID Connect reference implementation, where a nonce was not checked at login time. This flaw allows an attacker to fix a victim's session to an attacker-controlled account. As a result, although the attacker cannot log in as...

  13. MediumCVSS 6.9 EPSS 0.47%

    NGINX Agent's "config_dirs" restriction feature allows a highly privileged attacker to gain the ability to write/overwrite files outside of the designated secure directory.

  14. HighCVSS 7.1 EPSS 0.17%

    NGINX Management Suite default file permissions are set such that an authenticated attacker may be able to modify sensitive files on NGINX Instance Manager and NGINX API Connectivity Manager. Note: Software versions which have reached End of Technical Support (EoTS) are not evalu...

  15. HighCVSS 8.1 EPSS 0.53%

    NGINX Management Suite may allow an authenticated attacker to gain access to configuration objects outside of their assigned environment. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

  16. MediumCVSS 5.5 EPSS 0.22%

    Insertion of Sensitive Information into log file vulnerability in NGINX Agent. NGINX Agent version 2.0 before 2.23.3 inserts sensitive information into a log file. An authenticated attacker with local access to read agent log files may gain access to private keys. This issue is o...

  17. MediumCVSS 6.5 EPSS 0.76%

    In versions 2.x before 2.3.1 and all versions of 1.x, when NGINX Instance Manager is in use, undisclosed requests can cause an increase in disk resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
