Directory ACL bypass in ProFTPD (through 1.3.9b and 1.3.10rc2) lets authenticated FTP users reach files inside DenyAll-protected directories by prefixing paths with /proc/self/root in the RNFR (rename-from) command. Because the CVSS 4.0 vector specifies PR:L, exploitation requires a valid low-privilege FTP account, after which an attacker can rename and then retrieve files that configured Directory ACLs were meant to protect. There is no public exploit identified at time of analysis and no KEV listing, but the VulnCheck-assessed CVSS of 8.6 reflects the strong confidentiality and integrity impact on file-access controls.
mod_sql in ProFTPD before 1.3.10rc1 allows remote attackers to execute arbitrary code via a username, in scenarios where there is logging of USER requests with an expansion such as %U, and the SQL backend allows commands (e.g., COPY TO PROGRAM).
make_ftp_cmd in main.c in ProFTPD before 1.3.8a has a one-byte out-of-bounds read, and daemon crash, because of mishandling of quote/backslash semantics. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required. Public exploit code available and EPSS exploitation probability 53.6%.
In ProFTPD 1.3.7, it is possible to corrupt the memory pool by interrupting the data transfer channel. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
ProFTPD 1.3.7 has an out-of-bounds (OOB) read vulnerability in mod_cap via the cap_text.c cap_to_text function. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Out-of-bounds Read vulnerability could allow attackers to read data from memory outside the intended buffer boundaries.
An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. Rated medium severity (CVSS 4.9), this vulnerability is remotely exploitable, low attack complexity. This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.

ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
The mod_tls module in ProFTPD before 1.3.5b and 1.3.6 before 1.3.6rc2 does not properly handle the TLSDHParamFile directive, which might cause a weaker than intended Diffie-Hellman (DH) key to be. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
The mod_copy module in ProFTPD 1.3.5 allows remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands. Rated critical severity (CVSS 10.0), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and EPSS exploitation probability 93.7%.
Integer overflow in kbdint.c in mod_sftp in ProFTPD 1.3.4d and 1.3.5r3 allows remote attackers to cause a denial of service (memory consumption) via a large response count value in an authentication.
