CVE-2026-115723Snap7 through 1.4.3 contains an out-of-bounds write vulnerability in the passive partner that allows a malicious active partner to overflow application buffers by declaring an... Executive summary The advisory says Snap7 through 1.4.3 contains an out-of-bounds write flaw in its passive partner component, which a malicious active partner can trigger by declaring an oversized length to overflow application buffers. The advisory text provided is truncated and does not state a severity rating, fixed version, or vendor recommendation. Technical summary The flaw is classified as an out-of-bounds write (buffer overflow) in the passive partner of Snap7 through 1.4.3, triggered when a malicious active partner declares an oversized size or length in S7 BSend data. The attack requires a peer that can establish a connection to the passive partner over the network, as the code accepts incoming connections matched to configured partner addresses; no authentication requirement is stated in the excerpt. The excerpt contains only source code from s7_partner.cpp and no fixed version, workaround, CVSS score, or detection guidance; these are not stated. The advisory text is truncated, so the exploitation details beyond the summary sentence are not fully available. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
