Package: apache2 Version: 2.4.53-1~deb11u1 Severity: minor
Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** Enabling cgid in apache2 (with a2enmod cgid) results in an error when using mpm_event: [cgid:error] [pid 8943:tid 140189712234240] (22)Invalid argument: [client x.x.x.x:49364] AH01257: unable to connect to cgi daemon after multiple tries: /usr/lib/cgi-bin/xxxxxx Meanwhile, the user receives a 503 HTTP error, rather than the CGI content. Upon launch, Apache creates /var/run/apache2/cgisock.PID (where PID is the PID in question), however it does that as the www-data user and root group, who does not have write access to /var/run/apache2 (where only the root user has write permission). To fix this, chmod g+rwx /var/run/apache2 fixes the issue. Since we're only adding the root group, this likely has a minimal security effect. Alternately, the default directive of /etc/apache2/mods-available/cgid.conf: ScriptSock ${APACHE_RUN_DIR}/cgisock Should not point to a folder that does not have write access by www-data user and a subfolder with more open permission should be created. -- Package-specific info: -- System Information: Debian Release: 11.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-15-amd64 (SMP w/4 CPU threads) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages apache2 depends on: ii apache2-bin 2.4.53-1~deb11u1 ii apache2-data 2.4.53-1~deb11u1 ii apache2-utils 2.4.53-1~deb11u1 ii dpkg 1.20.10 ii init-system-helpers 1.60 ii lsb-base 11.1.0 ii mime-support 3.66 ii perl 5.32.1-4+deb11u2 ii procps 2:3.3.17-5 Versions of packages apache2 recommends: ii ssl-cert 1.1.0+nmu1 Versions of packages apache2 suggests: pn apache2-doc <none> pn apache2-suexec-pristine | apache2-suexec-custom <none> pn www-browser <none> Versions of packages apache2-bin depends on: ii libapr1 1.7.0-6+deb11u1 ii libaprutil1 1.6.1-5 ii libaprutil1-dbd-sqlite3 1.6.1-5 ii libaprutil1-ldap 1.6.1-5 ii libbrotli1 1.0.9-2+b2 ii libc6 2.31-13+deb11u3 ii libcrypt1 1:4.4.18-4 ii libcurl4 7.74.0-1.3+deb11u1 ii libjansson4 2.13.1-1.1 ii libldap-2.4-2 2.4.57+dfsg-3+deb11u1 ii liblua5.3-0 5.3.3-1.1+b1 ii libnghttp2-14 1.43.0-1 ii libpcre3 2:8.39-13 ii libssl1.1 1.1.1n-0+deb11u3 ii libxml2 2.9.10+dfsg-6.7+deb11u2 ii perl 5.32.1-4+deb11u2 ii zlib1g 1:1.2.11.dfsg-2+deb11u1 Versions of packages apache2-bin suggests: pn apache2-doc <none> pn apache2-suexec-pristine | apache2-suexec-custom <none> pn www-browser <none> Versions of packages apache2 is related to: ii apache2 2.4.53-1~deb11u1 ii apache2-bin 2.4.53-1~deb11u1 -- no debconf information
